Since both Golden Age Captain America and Golden Age Marvel Mystery were fast-tracked in 2008, I'm guessing the fast-tracked book won't be GA. That leaves Atlas and/or Marvel as the fast-track book(s). Since Gormuu wrote "At least one of these books is a "fast track" title...," I'm gonna guess that they both are. So:

May, 2009 Iron Man #6
May, 2009 Atlas Era Journey Into Mystery #2
June, 2009 Captain America #5
