I wear old jeans, and wipe off the tip every 2 or 3 joints I make.
(Actually most of my jeans have the stripes on the upper right leg..)
This is a pic of the iron I use, not too expensive, but go ahead and get a small round, not a spade tip like it comes with.

I have used this setup for doing monitors, pcbs, pinball pcbs, xbox 28 pin mods, ps1's, and anything else I can think of.
That iron and a cheap solder sucker from radioshack will get 99% of all soldering needs done.
(Unless of course you need to get into smt..)
p.s. for cleaning the surfaces of what you are working on, very fine sand paper works, or I often use the needle tips of my multimeter to scrape away to the clean metal underneath the corossion.
(These are tips made to puncture through the insulation of a wire, not the standard large tips)
