Do yourself a favor and get good gear. If you dont have the money, save for it and get one thing at a time. The soldering tweezers are junk unless you get the $200+ Hako models, get a decent hot air station. The $100 Chinese ones are not bad. I used one for a long time and it served me very well. Get one of the GOOD solder suckers. The blue and yellow ones, not the crap metal small ones.
As for desoldering, get the hako gun. Its only $250 if you can find it on sale most of the time.
