What he said, and take a compressor to blow the dirt that gets trapped by the heat shields. Take a blow gun and blow around the plug before you take it out. Use anti-seize on the new plugs before you install them. It's sold at auto parts stores.
Not required, but worth the extra 2 minutes.

And if I might add my three-eighths of a cent worth:
Blow the crap out of the heat shields before applying the penetrating lubricant so you don't make mud.
Anti-seize should be considered mandatory. It's easier to apply anti-seize today than to extract a broken plug during the next tune-up.
If any of the plugs are difficult to remove, grind on the way out, or show rust on their threads, chase the threads (in the head) with a thread chaser (not a tap).
