Good luck, Peter!
The Pi is (at least) a 6-layer PCB, so you may need to pre-heat it a little to make life easier. You will need a good flux when removing the cardholder and gentle lifting until it becomes free. Clean the pads to get them as smooth as possible. Flux and solder wick are all you need.
Any lead-free solder paste should be OK for the replacement. Personally, I use a SAC305 paste for manual assembly work, specifically SK P2-5 SAC306 88.5 20-30 T4 from SolderKing, made in the UK :-).
Out of interest, do they still use Molex 1040310811 cardholders?
