Rock on, dude.
Contact them immediately, if you haven't already done so, and see if you are eligible to have the PMI removed from your loan. There is a percentage of balance after which you may demand this removed; it could knock hundreds off your mortgage payments. PMI is mortgage insurance; insurance YOU pay for THEM as a safeguard that you will make the mortgage payments. It's a crock, but it's standard. Have it removed if you qualify, the cutoff is usually 20% of the balance paid I think. It might also be known as MPI depending on your state.
