Default before flashing a custome rom??

Is there something i should make a backup before flashing the rom like unlock code or activation cuz im not in usa and my phone is verizon was giving to me by a friend works in usa and he said he bought it from someone came to his store.

is it sure that everything in the phone like networks (cdma and gsm ) will work just like now after flashing the custom rom??

If you are rooted and have safestrap, you can make a backup via that and then flash. ALWAYS, ALWAYS, ALWAYS make a backup before you flash a new ROM. As far as functionality goes after flash, it all depends on the ROM.
