I have only seen 3 armors in my life (2 of them in pics).
1st - ESB one which is 93% aprox AoSW and the Ab. plate is on the MoM (Forget the gauntlets).
2nd - RotJ one, used for the MoM except for the Ab. plate, which was used in ESB and in RotJ as Hero.
3rd - The RotJ Stunt with red portions. I don't know where it's, maybe the archives.
Then 6 helmets were made. IMO the white helmet all the pics came from (with the dent add) is the ESB version helmet (before paintjob). Also the armor of the Supertrooper video is IMO the ESB armor, with the chest plates too curved.
About the jet packs I know about... 1 for PP#1/#3, one for PP#2 (stolen), 1 for ESB (maybe it's a repainted PP#1/#3 but I don't think so), and 3 for RotJ (1 is FOAM, 1 is the stunt of AoSW, and the other one is the MoM one, maybe one of the last two mentioned is a repainted ESB JP, I don't hope it so...).
