The tools you need a soldering iron and a desoldering tool such as a solder pump or solder wick.
The best advice I can give you is to practice your soldering skills on something else that you don't mind ruining -- old nintendo or sega cartridge, old battery powered electronics, etc.. so you get the feel for how to remove solder off of a circuit board. It just takes practice and lots of patience.
just like MPC Hunter said. practice, practice. and dont hurry. chill. Watch some youtube vids on how to desolder and solder and get all the unnessecery electronics out of your cellar and practice.
