Does anyone know someone in the Boston area that can help me replace braze-ons on a road bike? Is this typically done at the LBS?

Peter Mooney at Belmont Wheelworks might do repairs
Independant Fabrication in Somerville might do repairs
ANT (AlternativeNeedsTranportation)might do repairs
What is the braze on you are trying to replace?This can be expensive and there might be a clamp on part for much cheaper
