Well, if you have CWM ( Clockworkmode ) already, you can use the ones without.
I am suggesting to just get the PREVAIL_M820_FA19_Rooted_CWM and then the ROM ( CTMod3.68 with kouma kernel, or 187MoD or CyanogenMod 7 or any of the ROMS) you like.
I like CTMod, other guys like the cm7........... it's the personal taste.
Can I just leave it on stock rom? I am just doing this so she can have a bit more room on her phone. And I don't think she would utilize CM7 or a kernel to their full potential.
