One other thing - out east, there is real rain, so plan your travel according to that. The hurricane season is shaping up to be a big one, so there may be better water further south. If you get the chance to do it, the Watauga is the sweetest creek I've ever done and is worth the 300 miles. It has some relatively good gradient and a couple of soft (at most levels) class Vs but for the most part is low-stress, but solid class IV wilderness creeking. There are about a thousand boofs in the five miles and you can easily lap it. On the boof-o-meter, I think it's even more fun than the Narrows of the Green. Plus you can always tag along with the college kid who run it 3-4x a day and get beat and a shuttle.
Also, if you wanna huck big-time or run the hair, the Watauga is right by the Elk, which has some biiiiig (read: LVM-size) waterfalls.
I think Southeast Whitewater by Monte Smith is out of print, but that is a great guidebook for the area (notwithstanding the fact that he's an open boater who seems to think that class III+ means "experts only"). If you fused the kind of smart beta and sheer amount of useful info in that guide with the cosmetics of CRC, you'd have the ultimate guidebook.
