Default [Q] SAMSUNG Note II E250s Please Help

Guys. Please help. I'm new to flashing roms and technical stuff with my note 2.

Can someone post links for custom roms I can use for my samsung E250s.

Im also confused on what flashing in kernels are for. I have downloaded Thor kernel and I'm not sure if I will flash it to my device and what will happen.

Sorry for all the newbie questions. I hope someone can help me on this concern.
