You need to ROOT the device, install CWM or TWRP recovery (from the Play Store), then follow the directions in the thread of the custom ROM. If you have a non-rooted ICS phone, pay careful attention to the unlocking and rooting instructions: the bootloader is locked.
Best ROM? Pull out the daggers....
I'm of the opinion that Gingerbread ROMs are best for the P970; they are stable, fast, reliable, and every component works.
ICS ROMs for the P970 are fairly stable, but subject to freezes, lockups, quirks, and everything else.
ROMs after ICS (Jellybean & Kitkat) are very quirky, with some componets outright not working.
If I were installing a ROM on SOMEONE ELSE'S PHONE, I would install either
Zeus 6.4 (from this
Link) or
Marvel 9 (with this
PATCH).
