Help a nub on how to root mt4gS

[JESTERx626]

As a first timer, reading thru multiple threads about rooting and new technical names is a whirlwind of WTF. I felt it was better to post here as I own a mt4gS and someone else here with the same phone can assist me, dont know if that matters or if any root thingy works for all androids. What I want out of this is to remove things I dont need. I would like better battery life, and wifi tethering. If someone can point me in the right direction as easy as possible that would be great. thanks
