All gunshops and commercial (not necessarily the hobby types) gunsmiths are FFL holders. Most gunshops will do transfers, some will charge more than others so look around but remember to try to support your local gunshop/gunsmith when possible. I also handle transfers (center of the state - State College area). Typical charge is around $20 (which should include the PICS paperwork). Also, if the FFL does not know you or the buyer/seller, they may want to run the serial number of the firearm to insure it has not been reported stolen. Don't take offense if they want to do that, they are only looking out for you and their business (selling/transferring stolen firearms will land you in heap big trouble with the State and Feds.

There are several publications that will give you a good estimate on the value of firearms. The Blue Book of Firearms is one of the best. A local gunshop should also be able to help. Just like cars though, if you are going to spend your money at that gunshop, they will probably going to give you a little more that if you are just looking to sell outright to them. If you are going to sell outright to anyone, then get an estimate of what it is worth and then add extra to get to what you think you can sell it for.

If you're frugal, you can go into a Barnes and Noble or other big bookstore and peruse the firearms books (I know the local B&N carries the Blue Book of Firearms) to get and idea of the worth of the firearm.
