What are you riding now? What components - groupset, seat post and saddle, bar and stem, crank and BB, etc? Do you have a weight target or just opportunistic savings?
* For the little bits you're after plus more, Starbike (site sponsor) has you covered. Fairwheel, bikeonlineit, etc are other good options. Look at Extralite's delrin (?) or Tune's magnesium spacers in addition to the usual carbon ones.
* You'll have no issue finding a grundle of seatpost clamps in the 5-10g/ea range. Consider pairing it with a sub-200g post and sub-200g saddle.
* Bars and stems can be another are for "cost effective" weight savings. You'll have lots of for sub-100g stems and sub-200g bars to choose from.
* You may also wish to check out a lighter cassette and chain to achieve your weight savings goal, though they're likely to wear faster than "heavy duty" bits (105, Rival, etc).
* For bolts and such, add Toronto Cycles to your list of sites to check out.
Have fun and get that wallet ready!
Here is my complete bike specs. Ideal overall target is just getting to 6.8kg, but for right now Im just buying some extra little things. Stuff like the seat and handlebars are subject to change during my next fitting. I will be limited to what the bike shop has on hand. I also have yet to cut the seat post and steerer, and will be getting some lighter bar tape with the fitting. The bike currently weighs 17.2lbs with pedals, computer mount, and bottle cages:
