Right now there are 2 different ASF boards in production. The original (RA-18) has the standard servo motor for all previous models and the second gen board (RA-22) has a coreless motor that fits the MR03 servo.
The easier swap would of course be the RA-18 since there's nothing else to do other than appropriate wire length and placement and (as mentioned) cover swaps for a neat appearance.
The RAW-22 swap would be a tiny bit more involved (requiring a servo motor swap) but I think if you wanted to do away with the reverse lag of the RA-18 it might be the way to go.
I plan on building an F1 with the RA-22 board myself... I love the better response time of this board compared to the original ASF model.
As for your other question, I don't think you need to swap terminals to gold. I don't think there's that much of a performance gain to bother with the extra expense for the number of cars you have planned.
