Good going; stick dem fish.
As far as equipment goes, find what you like. I would recomend upgrading the rest though. Check out backwaterbowfishing.com Good stuff; for a rest try the bighead or quickdraw, they're some of the best.
I live in south Louisiana. I got lots of water to hunt, both fresh and salt. I'm in Iraq right now, but I'll be going home on leave next week, so I'll be doing some bowfishing. I'll let you know how I do, maybe post some pics.
Here's a few old pics:
