Thanks! And I'll definitely be buying solder wick to add to my kit!

I'd suggest figuring out a way to fix it in place as well... As for your desoldering technique, it's ugly but it works ;) Sometimes clipping the part then pulling the leads out one at a time is just easier. Protip: Solder Wick is your friend. Oh, another thing too, it's frequently easier to desolder stuff if you apply extra solder to the joint first, gets some fresh flux into the mix.
