For small components a tweezer style soldering iron works ok, though
I'm just as liable to heat one side a lot, then apply heat and force
to the other side quickly.  Typically it overheats the part, but it
may still be good.

The multi leg SMT parts are trickier.  A hot air rework station with
the appropiate nozzle works very well.  If that's not available then I
have used solder wick along with an x-acto blade to lift each pin up
while it cools.  Takes a long time, the pins don't ever really lay
flat again, but the parts are generally usable.

Good luck!
