If you lift of a pad you need to super glue it back down on the board, let it dry. If the track is ripped use some flux and solder it back to the other side. You will need a meter to check to see if the fix worked.

When reworking capacitors revome the old part, clean with 100% alcohol any goo left over, remove the old solder with an iron and copper braid, re-tin with solder, then put new capacitors on. I suggest you use the old rosin-lead solder and not the new lead free junk (less cold solder joints).
