While building the MP573, I realized I had soldered in one of the small signal transistors (Q1-Q5) backwards. In attempting to get the transistor out of the board, one of the leads broke off at the body of the device. So...I'm able to source from DigiKey or Mouser a transistor, but it's not the exact unit, I don't think...I can get either a BC550CTA, or a BC550CBU. Will either of those work ok?

They are the same. The difference is in the leads spacing. They both will fit.
