Thanks for that, unfortunetly I don't have access to a computer at the moment. I've heard of some being able to do this straight from the phone itself.

Rooting does not brick your phone. Once you root you need to install a recovery and make a backup. Once you have a solid backup you can flash a rom, add a theme, and over clock.
I felt the same way before I rooted. Now, I change roms on a regular basis. Plan on do so tonight. Bottom line -- you need to be comfortable. If you are not then do NOT root. Continue to read and ask questions.
Forgive your enemies it messes with their minds!
