Well, the main hazards were:-

-Heating the pads too much so that they came away from the PCB
-Trying to remove the IC while it was still attached to some pads, resulting in the pads coming away with the IC.

Neither of those things happened, so well done!

If you have some 'proper' PCB cleaner or something which will do (suggestions anyone?) you mind find those burnt looking bits are just left over burnt flux and will clean off.

I would say you have done by far the hardest bit. Do you have a socket you can fit in the holes where the IC was removed from?
