And the little "W" on there, do I line that up with the one on the head?

Reusing head gaskets is always a bad idea. Once they ar crushed (used once) they have to much potential to not work right (leak), besides they are to cheap not to replace with new.

Well its already ordered, so I guess i'll wait.
But, just out of curiosity, what kinds of problems can occur with a used head gasket?

Greetings:
If the gasket fails to seal properly, your compression and therefore power will be low. I have no direct experience with hotspots and other demons, but I've read about issues affecting longevity as well as lost power.
Blowing mixture and oil out the crack will make a mess, too.

A blown gasket with an aluminum head can also create a groove in the head but the hot gasses as they move out of the cylinder.

I have never re used a head gasket, its too risky for your engine. It creates a lean condition, air leaks, and can make the piston do a poof-kaboom.
