Thanks 
I do have a Rhino Tools desoldering station ( https://rhinotools.com.au/product/desoldering-station/ ) but I haven't quite mastered its use. I had it set at 290C and I was probably being a bit too impatient/aggressive with the desoldering, or the board was a bit more fragile that I thought. All part of the learning curve, I guess. I don't use the solder sucker any more because I know of its pad-lifting tendencies, and I've never had any luck with desoldering braid. I'll definitely try clipping the pins next time; I hadn't thought of doing it that way 
. I'm still not very good with all this stuff.
The pads that lifted from the motherboard were on the 7805, so I might have to get the keyboard off to desolder it properly? At least then I'll have it prepared for the replacement kit Is it worth trying to repair the broken pads? I've used copper eyelets on homemade PCBs in the past, though I heard some people use copper foil and epoxy. Or is that just kind of an aesthetic thing?
