Am I looking at 100, 200g? Would you upgrade from the am classic post to the use carbon one for 85 clams? Should I invest somewhere else?
I personally think Chorus is fine, as good as Record really except for a few bolts, logos and lots of $$$.
Better than Ultegra??? is a never-ending debate....They're different, not necessarily better. I don't know the total comparative weight savings: you can look on the Listings here or on the respective websites for the specific components you would use.
On the AC (you mean aluminum I assume?) versus Alien carbon you can expect to save 40/50g, not bad for $85, if you can stand the USE clamp. I think it's a PITA.
As others have pointed out, your money on a crit bike is better spent on durability/response/power than on non-rotating weight, like on a seatpost. I would spent the money on the best fork you can get that works well with your frame, and then on wheels (but the AC's you have in your budget should be fine).
