T2i is also a great camera to start off with, especially if you are trying to save money for lenses. It's almost the same as the T3i as far as specs. If this is gonna be your beginner camera, have you considered buying used? I buy almost all my equipment used since this is such an expensive hobby, and have had no problems.
Couple lenses that I get good all around use for are my 15-85/3.5-5.6 EF-S USM
and EF 28-135mm f/3.5-5.6 IS USM for outdoor shots.
I shoot a lot of outdoor and candids and don't like cropping, so zoom is also important to me. I own the nifty 50 also, but rarely use it due to no zoom capability.
