How to change aperture, shutter speed, ISO, and exposure on a Nikon D40?

I'm a new photography student and just got my first DSLR camera. I already finished a semester of Digital Photography class, and we learned nothing about any of the things I mentioned in my question. But those seem to be the 4 basic principles of photography from what I have been reading online. I can't figure out how to change them on my camera at all. Could someone please tell me step by step (including what buttons to press and everything) for each thing? I'm so confused. I mess around with my camera and think I'm changing them, but my pictures never look any different. Please also explain what each one of these things does.

Did I damage my focus motor? Newbie here. Nikon d7000?

Hey guys so I want to begin by saying I'm totally new to DSLR photography.

When I first received my Nikon d7000 a couple days ago I latched on my 50mm f/1.8d lens. I didn't even know pressing the shutter button halfway down focused. So what I did for my first probably 10-15 shots the first hour I got my camera was I manually focused the lens by moving the lens focus ring then I would take the picture. All of this while my Autofocus was set to on. Now I realized my mistake relatively quickly and started only using the autofocus function. I didn't notice any problems but I read online the following day that that is a huge no-no. Especially with a lens like a 50mm f/1.8d because it uses the d7000 internal focus motor. I got scared when I saw posts saying that the internal motor has got to be damage/stripped/whatever.

However, when I was manually focusing it I didn't experience any hard resistance like other people talked about. Was it because I wasn't pressing the shutter button? Just manually focusing and then pressing to take the picture.

I would just like to here some more opinions on if my focus motor is probably damaged or not. What are some of the signs I should look for if it is?

I also have a Tamrom 70-300 vc and on some pictures it won't focus and take the picture. Is that a case by case basis and the camera settings or could it be linked to what I described above?

My photo's don't look the same on different (colour) on different computers?

I have a nikon d7000 and i shoot using automatic settings, I've noticed my photo's aren't the same colour on different computers, is this just the computers screen resolution or should i start shooting using manual setting?

Is this lens compatible with Nikon D3200?

I wonder if Tamron 17-50 2.8 is compatible with Nikon D3200.

How much should I charge for taking pictures?

I'm not a professional, but I know what I'm doing and that I do good work. I've been contacted by quite a few people to take pictures for them. (Weddings, Couples, Children, Senior pictures) But I'm not sure what I should charge and I don't want to over charge because like I said, I'm not a professional, but I want to be able to grow as a photographer.

Any input or opinions will help, Thanks.

Also, I have a Nikon D3100 if that matters at all.

Added (1). I'm pretty sure I don't need "a business license, a tax ID, and good liability insurance" for something that is a hobby and not a main source of income. Especially since the money I'd get would be used mainly for printing the images.

Canon eos rebel, t3i, or nikon d3200?

I'm not really technical so I don't know how to use complicated options. I just want something with great quality you can use to take modeling pictures of people and close ups of nature. I like that the eos is smaller, but what has the best graphics for photographing people?

Added (1). by the way the modeling pictures are just of me and my friends for fun. I want high quality and good lighting

How to take this kind of photo with a canon rebel t3i?

http://bathroomstallfame.tumblr.com/
k i'm not sure if you can see but her profile picture has a little light leak looking thing and i was wondering if anyone knew how to do that on a canon rebel t3i

she said she had a Nikon D90 and I put it on "p" at night and it sounds like the camera is taking two pictures so between clicks move the camera a little and the light will move accordingly

does anyone know how to do this on a canon?!

Prime lens for NIKON to match my needs?

I purchased a Nikon D5100 a few months ago and I'm slowly learning about it. I have a basic understanding of aperture, iso, shutter speed, etc. I have the kit lens and it came with an additional (telephoto?) lens as well. I adore my second lens (I'm sorry! I can't remember what it is exactly… Still learning!) but I have to stand too far away. I'm not a professional and would rather leave the serious stuff to the professionals. I mostly do portraits of my family and some personal events. What I'm looking for is honest advice on a good lens that will serve my purposes. I want something that can take attractive portraits and yet be general enough I will not have to change out my lens constantly. Since my photography is for personal use, I can't justify spending thousands on equipment. I'm hoping to find something that will let me achieve a nice bokeh without having to stand in the other room. Also, and not sure if this is even possible, I'm looking for something that will work well in low-light so I do not have to use the flash. Since most of what I photograph is candid shots or children, a slightly quicker lens would be appreciated.

For example, I want to take nice photos of my niece and nephews birthdays with a few crisp portraits I can frame for personal display. I also attend fundraisers for work, anniversary parties… Etc and want to take nice photos that are dimly lit indoors without blinding everyone with flash.

If there's not a lens that is affordable ($500 or less range) I understand! I just am not sure what equipment I would benefit from the most to add to my arsenal.

What microphone is best when using a Nikon D3200 for interviews?

I'd like to have a wireless one or the kinds that sit on a table during a conference call. I'm a beginner at this and don't have a whole lot of cash. All of my work is primarily for non profit use.
