One of the nicest things about having a rooted Note 2 is the ability to run custom Roms on your device. If you wait a week or so most of the popular Roms will be updated the MA7 (the recent update). If you are running ClockworkMod or TWRP recovery, simply flash the new rom after running a Nandroid backup of your current Rom. I'm presently running Whompasaurus2.6 and waiting for the new update. It is basically stock with several enhancements that really make the Note2 sing.
Frankly the update doesn't add anything you can't afford to wait a couple weeks on. Don't neglect reading up on proper installation.
