For 2-terminal parts, use a soldering tip that is wide enough to
contact both pads. Heat both pads at once (add some solder if
necessary) and push the part sideways off the pads. Then clean off the
pads with solder wick, and you're ready to install a new part.
If you don't have a hot air soldering tool, and you need to remove an
IC, and you don't mind destroying the part, heat up the legs one at a
time, push them sideways off the pad, and break them off. Don't try to
cut the pins with cutters - it may damage a pad.
Cheers,

But part of what I have to do is remove just a few SMD resistors in a larger field of many such devices. I'm thinking that I'll have to heat the whole board and loosen all of the SMDs and then just pick off the few that I need to. It seems to me that the easiest way to do that will be with some kind of vacuum tool. I think I've seen tool that were operated by actually sucking on a tube in order to pick up the SMD. I also think that I've seen a DIY device that used an aquarium pump to supply the vacuum.
