Hi.
Im really not having a go here but i agree with uber, give the damaged boards to a repair specialist as they will easily be able to repair these boards.
Get yourself a few old 360 boards, some flux, high quality solder and tip tinner and a good quality 25 watt soldering iron and practice on the old boards.
I use antex soldering irons and i have no problems, it is well worth spending the money on a good one as cheap irons will just mess things up
