Tiso produce a "Screw Kit" that replaces almost every bolt on a groupset.
It is available for Shimano DA, or Campa' Record.

DA actually uses quite a few alu screws stock, on the RD and FD for limit screws. Other then that I think use of alu is too weak for the applications.
SRP has Ti clamp bolts for the shifter/levers, this saves 4g.
Avoid SRP for anything else, as they are a rip off. For all other Ti bolts, which are much better then using aluminum anywhere else, go here

Very high quality, I have delt with a few others, none as good. Avoid

There bolts are crap.

Don't buy a kit. It is WAY cheaper to figure out what bolts you need and just order the individual hardware. I have only used a couple of different suppliers and thought Redmist Fasteners was the best. http://titaniumfasteners.com/shop/
I haven't tried tekbolt though.
Read Nino's bolt article on this site, and if you decide to use aluminum, buy or borrow a small torque wrench.
5mm bolts can be tightened to about 4Nm and 6mm bolts to about 5.4Nm. Where people usually get into trouble with aluminum hardware is they over tighten it or they reuse it. If done right, alu can be used for derailleur pinch bolts, (road) brake pads, brake pinch bolts if they are 6mm (I only trust it on the rear,) r. derailleur pulley bolts, and r. derailleur pivot bolt. DA already uses alu. chainring hardware and (as SL pointed out) limit screws. I am trying to break an alu. f. der. braze on mounting bolt (with aggressive trainer riding) and it seems to be holding up so far. If you have a clamp on f. der alu. is fine for that too.
Alu. hardware doesn't save THAT much and the peace of mind (especially on the brakes) is worth more than that to most. But this IS weight weenies and that is what I am comfortable recommending.
Oh, make sure your bottle cage bolts are aluminum and your aheadset cap bolt too.

I've also used www.titaniumfasteners.com and would highly recommend them. Pulley bolts and the pivot bolt are not stock and can only be bought from SRP.
In tuning a 7800 DA rear mech. Buy a SRP kit. Comes with a Ti cable bolt. I'm switch this for an Alu one.
You may also want to consider a carbon fibre mech plate from fibre lyte. Only saves a few grams but does add a certain BLING factor.
