I suggest to read these 2 books which will give some good tips and understanding for various types of shooting.
The first one I think everyone should read. If you don't know the relationship between ISO, Aperture, and Shutter Speed (or if you can't even spell ISO, Aperture, or Shutter Speed
), and how these 3 factors are inter-related, then you are not a photographer. You would be floored to know how many "photographers" do not understand these concepts. Don't be one of them!
The second is a great reference book to keep in your camera bag.
Understanding Exposure, by Bryan Peterson

The Digital Photography Book, by Scott Kelby
http://www.amazon.com/Digital-Photog...otography+book
Kelby has a whole series actually, I need to get the others but the original is excellent to whip out and say, "oh, night shot, tripod, ok here's what you do"
On the lenses I'd recommend an EF-S 10-22 but that's just because I had one. It's an awesome Canon UWA lens, incredibly sharp, and very valuable.
I bought mine new in June 2006 for $600 and sold it in Dec 2012 for $500.... that's 6.5 years of use for $100
Although to be honest I wish I hadn't sold it. It was that good.
