Like I said in the other post, you should maybe consider not getting a PDI chamber, because the 2 arms are a total PITA to work with, and my mag-catch mod works the same way as the 2 arms. A one-armed chamber like this one (http://www.airsoftsniperparts.com/apps/webstore/products/show/2494597) would be perfect. Or, you could get a single arm for the PDI chamber, designed by Cheeseman (http://www.shapeways.com/model/597729/type-96-hop-arm-combined.html)
Secondly, those barrel spacers ONLY work with EdGI inner barrels, which are now extinct (I believe). The barrel spacers will NOT work with the Prometheus barrel. Just make your own barrel spacer out of paper or duct tape.
Thirdly, I would recommend an EZ-LRB as your barrel extension. It incorporates the LRB system, as well as provides you with a nice looking muzzle. http://www.shapeways.com/model/572126/8749dc1443efd882f6161372a6357e7c
Lastly, for buckings, I would recommend a REAPS AEG bucking, hard. http://www.airsoftextreme.com/store...oduct_info&cPath=443_444_450&products_id=6109 You might want to consider pairing it with a PCS or H nub so the REAPS' bucking nub doesn't "bow out."
However, if you don't like my list, then, yes everything on your list will work EXCEPT for the barrel spacers. You canNOT get Polarstar or EdGI spacers for your gun as they will not fit the Prometheus inner barrel. You will have to get another brand, such as Prometheus' hop up spacers or maybe PDI (as long as the product description is not for the 10 mm Outer Diameter inner barrels).
