Questions about rooting?

http://forums.androidcentral.com – Sorry if this is the wrong place, I couldnt find a thread about rooting and I have a DNA... First thing I want to know is if I root it will it erase all my stuff? Will it make my phone slower like jailbreaking does to Idevices? Can I delete some of the stupid apps you are forced to keep?(reighn of amira, audible, etc.) (HowTos)
