OK, sorry about the lateness.
So, milking for wool, has only one drawback, you can't milk the creature for regular milk/cheese and wool. Whichever set you have last in the creature definition will be what you get. But, you can define the regular process under the female caste first then define the wool milking under the male, and the game at least will think all the products are available, so you could trade for regular sheep milk and cheese for use in the kitchen, but just don't try to make cheese out of traded for milk, it turns in to wool.
Speaking of cheese >:p It was the answer to my problem. As with everyone I ran in to the problem of having my milked wool in a bucket and no way of getting to it. That's not right i thought! The game has no problems getting to it! Why... shoul...
!!!!!
So, I let the game get my wool out of the bucket for me, then processed the resulting cheese in to wool thread.
I also added a wool tissue layer to the sheep and the ability to get some wool (5 actually) when you butcher one.
wool tissue...

and there you have it.
edit: one thing though, the wool cheese doesn't play nice with other 'real' cheese so I suggest you make a separate stockpile for just the wool milk and cheese and exclude them from your other food stockpiles... if it gets mixed in barrels with the other stuff it locks the barrel down until you separate them out with 'take from stockpile' orders. And the material values are just wild guesses, so if it turns out to be insane just lower them... haven't really tested that end out,
