I would

1. Ditch the tubes and go with stans. While your at it get some lighter faster tires. If you are racing Nokian NBX's are a good choice. They work well for me at least. Specialized tires suck
2. What crankset are you running. An American classic or Fsa platinium pro BB would save some weight. Truvativ Stylo teams are pretty light, and reasonably priced too.
3. Eggbeater Ti's would save quite a bit if you get the triples
4. Checkout Weightweenies.starbike.com. You should be able to find your parts listed, and compare with new stuff to estimate savings.

- Just knocked 3 pounds off a Demo Stumpy bike Specialized sent my shop by changing Wheels, Tires & Tubes! - Good ol' XTR hubs, Ceramic 517's and Bontrager Jones ACX Kevlar tires (light ones, you gotta watch em' they vary in weight alot) and Specialized Turbo Tubes......

Stans No-tubes

www.notubes.com. I hear alot of debate on here about Eclipse being better. No stans is better. I have never used Eclipse so I cannot say, but I use Stans sealent to put regular tires on my UST wheels and it works better for me than anything else I have tried. You should go tubsless whatever way you chose to do so

For wheels, you could get a set from Mike Garcia, with WTB hubs(if you want disks), this would knock off alot of weight and is not overly expensive. He can be reached at www.oddsandendos.com The weight savings would be in the hubs.

If you do want disk brakes, then it would be a good time.
For stem, A syntace is a very good option. They can be found here...
www.light-bikes/sales.com and the eclipse sytem can also be found there.
As for a seat, well every one has their own opinion on whats comfortable. But you can loose quite a bit of weight there.... the Selle Italia SLR is a popluar option.

Nice Ride...

Looks good, but I can find quiet a few sports to save weight.

Wheelset: You mention you wanted to upgrade to Disc Brakes, so it looks like a new wheelset is up on the cards anyways... Stock wheelsets are generally Heavy as they use heavy hubs, heavy gauge spokes, brass nipples, low quality rims etc...

The stock wheelset from my Avanti was/is almost 2000grams (is over actually), my new prospective wheelset is 1730g, Thats a UST, disc wheelset... It's one of the easiest places to save weight on a stock bike, and the most benificial too. Check out Mike at Odds and Endos.

Tyres: Rugular tyres should be under 550g and roll pretty decent- Check out Nino's "Tyre Rolling Resistance Data" posts theres quiet a few of them around. You shouls be able to find something that rolls fast, and suits your conditions, and style under 550g. Also Look into Stan's or Eclipse tubeless systems.

Stem, Bars, Post: An easy place to save weight, as most stock items are heavy, as are the ones said to be "light" (i.e Thompson) checkout the listings at WeightWeenies to check out some weights... Matching Kit looks best, but isnt always the lightest.

Thats it for now- i could sit here forever...
