As far as building your own hybrid goes just try different settings till you find something you like. The nice thing is you can always change it if you don't, I will caution you about the .90 radio code. It caused a lot of issues for a lot of people random reboots, VSOD's (Verizon screen of death). Other than that just pick and choose and have fun. About the time you find something you like another leaked OS will drop, and you get to start again. As far as unlocking your phone you are correct.
