Ed Hetzler has a site where you can practice along with them done up nicely as MIDI's.

Old Time Music MIDI Archive. Most of the arrangements are from the Fakebook, he has said, so they should match up well. I think doing a whole bunch of listening, there, could help. Also he has some cool software downloads there as well as slower versions of some tunes-- it's a good idea to plumb the site thoroughly because it has goodies here and there that are not so obvious on first glance.

Good luck!
