Boy, did you leave yourself open for harrassment! Let me start, yes, since the brake pads (brake shoes are however) are in no way connected to the wheel cylinder...
I would assume that you will have to remove the shoes. It is pretty tight in behind them and they do rest on the end of the wheel cylinder via the little dogs. May be possible to just release the hold down pins though and slide the shoes out a little. When I did mine last fall, I replaced everything, so I can't say for sure but would say that you will have to remove the brake shoes, pads can be left as they are!
