You definitely need some soldering experience but the repairability is not that difficult. The soldering points are big enough for any cheap ($40) soldering iron can get too. As for removing them, it helps to use flux and also a soldering wick to absorb all the old solder. It is not easy but not the most difficult repair. P.S you do not need the expensive soldering stating with hot air etcetera. This works perfectly as it get hot beyond the required point to melt the solder

Mick, the camera you got with your new screen should work. But since obviously it's not I'd suggest to transfer the old one. Very simple and won't take too long!
