Quoting L☮J:" Definitely. It's got a better sensor too, so you're pictures will look much nicer.   No problem!"

Great!!!! And thats the only lens I'm going to need right?? Do I need anything else for the camera??

The 50 will be great for indoor and outdoor portraits, and just for random snaps  

You will definitely want some sort of bag or case to keep everything in. And if you think you need it, a tripod.

Oh and a high speed memory card.

Canons consumer level cameras (like the T3i) are seriously super cheap feeling. But in all honesty, go to the store. Get what feels best in your hands.
