Welcome to the board! I'm a 7620VK owner, too - it's an attractive guitar, and I'm always glad to see more of 'em around here.
Stuff to make use of the entire range... Well, Dream Theater and Steve Vai are the two obvious ones. Also, how's your chord theory? These things rock for jazz comping and chord-melody type stuff. And likewise for classical - in fact, there's a Bach prelude I arranged in the lessons section that works nicely on a 7.

Yeah, shameless plug...
Have fun with the new guitar!
