Thanks for all of your replies. I had a little trouble finding some of the articles and the 1999 book (contains all my notes etc.)I was using has a different article for 352.46 than the 2002. normally I put a sub feed lug in the main and a main breaker in the sub panel. The bushing was a stupid oversight but since the conduit was PVC I didn't think much of it. There are exceptions for the main breaker or disconnect which probably don't apply to me but it looks like I'll be installing another sub panel.
