A5

I've been doing woodball and speedball with my A5 for about a year now.  It is starting to wear and I'm looking at some new parts.  Right now im using hpa, r/t, flatline, and a 6 position stock that is broken but useable and nothing else done to the gun(that I know of).  Since do both woodsball and speedball I'm thinking about getting the J&J Edge Elite Paintball Barrel System, Tech T Cyclone Feed Upgrade kit, NCStar 1*45 Reddot scope, the UMP shroud and an Ak47 folding stock.  I definently can't afford all this stuff at once so it would be spaced out by 2-5 months so i would like to know what to get first I was thinking the Barrel System since that is one of the most important parts of a marker (not including maintaining your marker).  Any comments would be welcomed.
