I agree with SSCULLY, esp about the rotating 6 month CD's. You could also put part of it into a Money Market account, allowing access to it with out penalty(I think) down to a $10k balance. And, you have a great rate on your home loan, so, if you really want to pay it off, and the outstanding balance is such that you can, go ahead, but depending on your balance, and weather or not the mortgage payment is a strain, I would say leave it. Even if you make a large payment on the principle, your monthly payment would be the same, and only affect the final pay off date in the future.

You also have to spend some of it on your self, like you said, a trip, maybe a few parts, other wise you'll just end up bitter about the whole ordeal always planing for the future and not having any fun with it ever.
