Thanks BOWFANATIC!
When I got it back from work yesterday, I sat down, took a couple of deep breaths and started again -- this time with the nock. Since i'm shooting a string loop, it was not too hard to move it up and down a little. After about 20 minutes of playing with it, things started to click and I got the verticle issues taken care of out to 20 yards. After that, i get a small amount of nock low behavior but I've heard that's normal due to the lack of fletchings.
So I started to tackle the windage problems. I was looking at my arrows, and I don't think I could be over spined. I'm shooting the equiv. of carbon express TR6075 at 29.5" with a 125gr tip and 70#draw. Knowing this, I started mucking around with the rest and finally found a setting that seems to give perfect flight.
So, just have to tune the broadheads and I'm good to go!
Thanks for the help!
