So I just rooted my GT-I9505 using towelroot. I have installed SuperSU and Titanium backup has made a backup on my SD card. I have installed ROM Manager (v5.5.3.7) and did the Flash ClockworkMod Recovery thing, and rebooted into recovery, but saw no options to backup. Back on the app menu it displays 'Recovery Setup' and listed under that has Current Recovery: ClockworkMod 6.0.4.7.

What I am wondering is, what do I do next? I want to go to a stock (or as close as can be) android experience, so I was thinking of using CM11? How do I go about this and what else do I need to do before this? Just trying to make sure I do everything right so I dont brick my phone. Ive also seen mention about custom kernels while looking around for research. How will this affect me? Sorry for all the questions! Ive also seen mention about NANDroid backups? Clockwork Mod? Help! Im a bit lost.
