I may have seen your frame the last time I was at Excel.
I have the same handlebars, fork, and seatpost on my Lynskey.
You'll need to get a compression plug for the fork. The Beartrap device is an eyesore on top of not working very well. You can call Easton and they'll send you a compression plug. Or get an FSA one (Profile and Reynolds don't fit).
In my frame, the seatpost required more torque than usual to keep it from slipping. It also got scratched very easily. It's my first and probably last carbon fiber seatpost.
I made the mistake of getting a Cane Creek headset after always having Chris Kings on my bikes. After a few weeks, a knock developed that I couldn't adjust out. The CC headset cups were very difficult to remove. I had to bang away at them for 2 hours even with the proper tools. I've never had that much difficulty removing headset cups.
As for spacers, carbon fiber ones have never lined up flush with each other. I haven't had this problem with Al spacers. The solution is to just use one big spacer.
