Great job!
You might try Outspokin cycles on Huron St for QBP products.
They are the only one in town that sell Surly products so they most likely have an account.
You shouldn't have a problem finding a chain either.
I use those plastic tooth flossers to get the bad crap out of the hard to get spots on the smaller parts.
They work great and don't scratch because they are plastic.
