i personally use titanium backup,but there are several that prolly will work.
with titanium,you need to pro key,id strongly recomend to get it,its well worth the $7.
with tibu pro,you can freeze bloatware before deleting it. you can also do batch backup and restores of all your user apps,wich will come in really handy once you start flashing roms.
if you want to try a different app for bloat removal,just make sure it has an option to temporarily disable,or freeze,apps so you can run the phoen a couple days and make sure that things youve selected wont affect normal operation of the phone. after that,they can be permantly deleted.
-make a nandroid of your stock setup with all the apps
-make periodic nandroids of your setup as you delete things. that way if something goes wrong,youll have one to restore that you wont have to start from scratch with the freezing/deleting
