Hi Steve,
Oh heck, those aren't big mistakes! Many folks re-do their flap hinges at least once....
Hinge material is CHEAP - if you've bent the things out of alignment, just buy a six foot length, split it, and use half for each wing. If this is the most expensive replacement part you get, it will be unusual. Think about putting the hinge pin in while you rivet - it stiffens up the somewhat flimsy piano hinge, and might keep the loops aligned.
On the flap installation, Van's gives you two methods - the single long pin with the hole in the aileron bracket, or the split pin - cut the pin in half, and remove a couple of hinge loops from the middle of the flap and wing. Insert the hings from the middle, with a little "L" shaped bit you safety wire to the flap brace. Lots of folks do it this way - I personally find it much easier.
