Getting my s2 back from my one friend (GT-i9100P, I think 4.1 or 4.2 JB), what's the best way to root it? Also a useful/simple custom ROM recommendation, I'm new to all this

I want my S2 back ;_;
To root it, you can install a custom kernel via ODIN, or more simply, flash a custom temporary clockwork recovery via the stock one. Then with your new recovery replace the stock ROM with CyanogenMod.

Pretty much this.
