Not aware of a map, but I'll try my best to help with what I can recall off the top of my head. I'll work my way down the list on their website and try to be as accurate as possible (Disclaimer: I've never used Fast Lane):
Banshee - separate line at the entrance for Fast Lane (requires Fast Lane Plus), goes directly to station where employee assigns rows.
The Beast - enter through the exit (requires Fast Lane Plus), path will take you up to the back of the station where an employee will let you in a gate.
Firehawk - Sorry, I'm not sure on this one because I don't care for Firehawk too much but, if I had to guess I would say that it enters through the exit... Requires Fast Lane Plus.
Flight of Fear - Enters through the exit and goes right to the station. (Fast Lane Plus)
Diamondback - Same set up as Banshee
Delirium - Not 100%, but I believe Delirium has a separate entrance for Fast Lane and meets the line where the ride op counts the guests.
Drop Tower - Again, not positive, but I think this is similar to Delirium's set up...
Invertigo - Like Firehawk, I usually skip this ride, but I know the Fast Lane enters under the cobra roll, not positive on where it converges though. It either goes all the way to the station or converges right before the station.
The Racer - I believe this is another enter through the exit ride
Vortex - Enters near the exit, however you cross a bridge over the ride and meet the regular line in the station where the line stops and the employee controls guest flow to the gates.
Windseeker - Enter through the exit
Woodstock Gliders - New this year so I do not know
Backlot Stunt Coaster - Similar to Diamondback and Banshee
Zephyr, Monster, Scrambler, & Shake, Rattle, & Roll - I believe these are all enter through the exit (Shake, Rattle, & Roll has been completely refurbished for this season so that could be different this year...)
Adventure Express - Enters near exit, cuts over and runs parallel to regular line and meets in station, similar to Banshee & co.
Congo Falls - Has a separate entrance and meets at or right before entering the station... I think? Not one you'll have issues with waiting for though...
Dodgem - For some reason I remember it having a similar set up to Banshee, with a separate line that goes up to the front... however there's a good chance that I'm wrong and it's just an enter through the exit.
Boo Blasters on Boo Hill - Separate line at the entrance, converges at the load area.
Surf Dog - unsure
Race For Your Life Charlie Brown - Separate line at entrance, converges at the load area.
Flying Ace Aerial Chase - unsure.
Again, sorry for the uncertainty. As a local and season passholder, I don't need Fast Lane so I've yet to use it, however, I tend to pay attention to the Fast Lane stuff (at least somewhat) and that is everything to the best of my memory. Anyone feel free to correct me where I'm inaccurate or fill in the couple I couldn't recall at all.
Hope this helps.
