I second Andy's recommendations.
I am also a big fan or Mr. Budliger's work. Not that all great photographeras are great teachers (or vice versa) but it never hurts to have someone teaching you whose skills you admire. A small thing perhaps but I also like that the workshop website shows a woman shooting with a near-DSLR and not a guy shooting top of the line gear. It tells you that they approach this with a "all are welcome" mentality.
He also does some tremendous fly fishing photography so you have to think that macro isn't off the table either.
His site is here:

I do believe he recently had an entire article written about him in Outdoor Photography, again, for what that is worth.
And yes, get Andy's aforementioned book. A book like Andy's is a great follow-up to a photography workshop because it keeps the "guided" portion of what is great about a workshop but also let's you have some time to digest the recently gained insights on your own.
If you need the pieces that a travel agent would give you but that are above and beyond the workshop (where to stay, where to dine, what to do, etc...), this gang (the regulars on the boards) is great for that. Between the lot of us, we pretty much have the state covered from Massachusetts to Canada and from the lake to the river.
