I'm sure it would be not much of a hassle to hook up the coolant lines to the TB, I just choose to leave them out for simplicity's sake.
Hopefully the fuel delivery will be perfect with the barb into the TB.
Good luck on yanking the old TB off, mine was a pain. The old gasket kept it stuck so hard, I had to resort to wedging a board partway under the old one and jumping onto it... several times! Amazing..
