*Daily* Samsung Galaxy Note 2 Tips & Tricks - YouTube
Spend some time on youtube and watch this guy's vidoes. I think they are great.
BTW, concerning the need to root: I've rooted/hacked everything I've had going back to a Nokia 7110 and I have to say the GNote2 is the closest to perfect "out-of-the-box" as any phone I've ever seen/owned. The rewards for unlocking/rooting are very minor on this device. You get to remove some bloat (big deal this phone isn't slowed down in the least by any bloat) and you get some cute themes. But it's just not a huge gain. JMHO!! and YMMV!!
