I think the LHT set up you described will be just fine for the riding you will be doing. You can always change things out in the future.

Personally, I think the complete LHT is the best deal out there for a complete touring bike. It has the nicest set up. I got my LHT frame before they offered a complete bike, but if I was shopping for a touring bike right now I'd get a complete LHT, no contest.
