I love Grant Creek, too. Best way to get in there is to go via P-Bar Lake, Trail 76, then Trail 75 (Grant Creek cutover). Nice camping down in there by Grant Creek Cabin. Moonshine Park and Paradise Park are not as nifty as they sound, though. Dry, burned over, no very close water sources, etc. Possibly go down Steeple, but I don't recommend going down Grant Creek from Steeple--it will take you forever, climbing over all those dead trees. The trail crews have not worked those trails much in the past few years. Lots and lots of deadfall.
Then there is KP--might also be covered in deadfall. I'd call the Alpine Ranger district, ask to speak to Myron Burnett. He's the trail crew person, might be able to give you some pointers. He'll be able to tell you trail crew schedule, if there is one. They didn't have a trail crew last year at all!
Lower Fish Creek to Black River, then upstream along river is my fave, but it's not strictly in the Blue, as it is west of 191. http://www.hikearizona.com/decoder.php?ZTN=327
