Yeah. Most times I've attempted to do anything like this, it's ended in failure. Getting them off is easy, but you tend to end up pulling/destroying a few of the PCB traces in the process. I've gotten it right a couple times, but it's more luck than anything. Replacing SMD chips is a huge gamble and you risk rendering the whole thing unusable.
Also you'd better be damn sure that you're not going to need to put the original part back in. I've replaced SMD parts with newer versions that were supposedly 100% pin-compatible. Oops, they just didn't work in that particular configuration for whatever reason. But the old part is as good as destroyed once you pull it.
EDIT - if we're just talking SMD resistors or capacitors here, they're a lot easier. I wouldn't worry too much about doing that, though you should still be really careful and slow when you do it. IC's are the hard part.
