1) Would just heating and pressing solder wick against the pins work?

2) What "fancy tools" are we talking about? You mean dedicated desoldering gear? (I actually have a solder sucker gun but wonder if it will "suck" too much in this case).

Again, big thanks guys! This is all a lot of work but somehow very rewarding, like working on old cars or guitars I suppose (never did those; I'm sure some here do!).

1. No not for surface mount there is just a thin layer of solder under the pins I don't think wick would be able to clean that out.

2. In the case of smt parts probably a hot air station with a tip for SOIC packages so you can heat all the pins at once and lift off the chip, some even have a vacuum probe to aid with removing the part. A solder sucker will likely not be much use in removing the chip but if it has a good strong vacuum it can help with cleaning up the pads after, but again care is needed as too much heat may break the bond between the pad and the board and you could suck the pad right off the board.
