New to ROMs

What's up everyone I'm ready to root my VZW GNex...but I want a Tom that's pretty stable and one thing I was really looking for was one where it has all the software buttons at the bottom. Home back menu search and multitask..I'm less worried about the multitask... is this a feature that can be edited in CM10.1? Because that's one I was looking into. Aside from that any recommendations for a newbie? I'm tired of waiting for VZW for my updates
