Refinancing?

[desihop]

As soon as the house is in better enough shape to let an appraiser inside, we're going to pursue refinancing our mortgage to take advantage of the lower interest rates from when we bought 3 years ago.  Has anyone refinanced recently and has any tips to offer or other advice? We are also considering going from a 30-year to a 20-year term as well. Thoughts?

Oh, and in other news my Thanksgiving kind of sucked and our general plan is to pretend that Christmas isn't happening this year.
