Since your getting a tight bore I would not do any work in advance of that provided its on its way. You should experiment with a Systema bucking. This may increase the FPS or give you better range. Yes your CA gears will be fine with an upgraded spring you should be able to pull a PDI 210 with stock gears and a full c size batt. The PDI will net you a bit over 400 with .25. A CA 170 should get you your 360 plus a bit more. I would throw in a bearing spring guide when you do the spring change since the box will be open.
