Sorry going to have to disagree with the order to get things in
First things that I feel are 'needed' are
feed neck, ASA and trigger, yes the trigger does make a huge difference imo, it will improve your bps
A halo or even better a reloader b will go here, eggs just do the job, but i found that i didnt 'skip' as many shots once i upgraded to a reloader from an egg
After that, you might want to think about a better barrel, and as stated the lucky one is very decent, same for All American and freak
Then you might want to think about kick, consistency and efficiency, best bet for these is a 360qev and a firebolt or a lucky stage 1/2/3 combo
Also something you may want is a new set of detents since the stock ones can be prone to being shot out the barrel (or were in my case)
Some dye stickies never really go a miss either, helps a lot for comfort imo
Only after all of then do I feel that I new board 'may' be worth the money, in semi you wont get higher than 17 bps I wont imagen, and ramping your never allowed to play above 15bps
Then if want, since it wont improve the gun at all, think about getting a new body
A reg may be needed, since the stock ones can be horrible (make sure you strip and clean it before you deem it as this) or fantastic, let it get broken in and get a good few cases through it first
My opinions of course but I feel this is the best way to go
