The easiest way is to flash ClockworkMod recovery with fastboot and install Rom Manager. After that, download the CyanogenMod zip you want and flash it. Remember to select back up and wipe data. Those are the two toggle options in the flash screen.
It really isn't all that hard.

I would recommend trwp, not cwm
and if twrp, the 2.3.3.0 seems to be the stablest one.
you have to be unlocked.
this is for s-off. for s-on go the same way with the extra steps at the bottom.
1. put the rom on your sd card and extract the boot.img from the rom
2. put the gapps for 4.2.2 on your sd card
