Settings for a Nikon D90 at a party?

I'm not a professional photographer, but hope to be one day. I have a D90 that I'm still learning with. A friend wants me to take photos at her birthday party. She knows that I'm not a professional and I'm not being paid.So, please don't post about how she should hire a real photographer.

The party is in a low lighted cabin next to a lake in the middle of the day. We will be both inside and outside.

I'm using the 18-105mm 1:3.5-5.6G lens that came with my camera. Could anyone recommend settings for the best photos? I'll be doing portraits, group shots and random party shots.

Which stores sell Nikon d40?

I live in metro-area Iowa and am wondering which stores are going to sell the Nikon D40 camera, if any. I've looked a bit online and tried looking at Best Buy/other electronics stores online, but I'm not finding many listings of D40s. Do they still sell them in retail areas? I know there are newer versions of Nikon cameras, but I don't want to spend a fortune. Also, which lens does the D40 come with? If I buy the body online, or buy the camera with a lens, how do I know if it's the lens that I want? (I realize that doesn't make a ton of sense… I'm a fairly new photographer and I've used the D40 before and loved it, but I don't want to buy a camera online and have it come with a different or more specific lens than what it comes with originally.)

90's look in my photos?

Thanks

Anyone have any Nikon D7000 tips for getting sharp and very focused images?

I've had the D7000 for several months now and although I'm a very amateur photographer, I'm very FRUSTRATED with my lack of crispness and focus in my images. I have used a D90 in before and those images turned out incredible compared to anything I can get in my camera… That was with the lens that comes with it too.
I'm using a Nikkor 50mm/1.4, shoot in manual and raw. I have taken a few workshops, but still am not loving what I'm getting.

Any help?
