I finished an Artemis CCD camera kit last year, including some very 
small surface mount devices.

A small bit and plenty of magnification helps a lot. Also fine desolder 
braid so when you get too much solder bridging pins you can wick up the 
excess. One technique for soldering ICs is to flood the pins with 
solder, then use the braid to remove the excess, just leaving solder 
under the pins.
