Tips on shooting video with DSLR?

I have been into photography for a few years now and spent most of those years using a Nikon D80. However, I recently upgraded to a Nikon D7000 after getting a great deal from a friend.

I have never messed around with the video option on the camera, but a recent uni assignment is forcing me to get started on that. I'm required to shoot a short commercial video tomorrow and I've been testing the camera out all day.

I'm having difficulty in getting the video tack sharp like some amateur videos I've seen on Youtube.
Youtube vloggers such as Charlieissocoollike and Kev Jumba seem to have really sharp videos and I know for a fact they're shooting with a DSLR too. What do you think? Is it due to lighting, lens, technique or anything else?

My camera is paired with a kit lens Nikkor 18-135mm by the way. Also, I messed around with the rotation dial and it seems to switch some numbers around on the display. Does the same concept of shutter speed apply for video? I can't imagine how… However, I do think that we can adjust the aperature to adjust the brightness of the video.Am I right in assuming this?

As for audio quality, I know that I shouldn't be expecting the best with this built in microphone… Infact, it was pretty horrible. My videos were all pretty much ruined by the sound of the wind and external noises. I expect to get a lot of these sort of assignments in the future, so I'm planning on investing on a good external microphone with a reasonable price. Can you guys give me some suggestions on that?

Any help is appreciated.

Is photography school really necessary?

If you aren't a self starter then - I get it. But if you have an internet connection and are genuinely interested in photography and have talent for the art. Then why not just youtube it, read articles and magazines and tutorials and practice? Learn by doing and experimenting?

My issue is, I have £600 that I want to use to buy either a studio lighting kit, or 2 Nikon sb 900's for my D7000. Mostly for portraits or models, max 3 models at a time. But I'm contemplating spending the money on the courses instead, although alot of what I see being offered is offered for free anyways on youtube… So why is it a good idea?

Does anyone have opinions about this Tamron lens?

So I'm looking for a new lens for my Nikon d3100. I was suggested by multiple people on here to get the Tamron 28-75mm f/2.8.It looks like a pretty solid lens, but I'd like to get some of your guy's opinions. If you've used this lens, what do you have to say about it, pros and cons?

Thanks!
