I don't grind my own wheat (yet. But I have this urge once in awhile. We'll see how long I hold out.)
But for anything bread related, I recommend the forums at www.thefreshloaf.com
I know they have lots of people there who grind their own, and any bread-related question you can think of, someone can answer. The forums are also searchable, so you might be able to find answers and tips in past threads.
