Hey Scrappy!
Welcome to the world of volleyball! Go into it with an open mind and ready to learn & I think you'll have a great time.
As refnrev said, there are several of us you may be familiar with from the basketball forum that also officiate volleyball. There are a bunch of great people in this sport, Jan & Felix among them - I have learned lots from both.
Another volleyball forum you might want to check out that tends to be more active than this one is the NFHS forum - here's the url:

Again, welcome!
