The first things that come to mind are the
then look into cassettes, brakes etc. I haven't looked into the wheelset yet but being carbon thats definately a plus. the other option is going single ring. any help would be awesome, cheers!

On my bike (stumpjumper comp carbon) I changed the saddle to a 95 g carbon one and changed the seatpost to a carbon one...
The original seatpost weighted around 270 g, and the original saddle weighted 278 g....
I also changed the brakes to XT becouse the magura MTS couldn't stop the bike (my weight is 68 kg). It increasd the weight of the bike a little but it was worth it.
In the future I will change the shifters to XTR and the cassate to XT/XTR (both will be lighter than the original one).
I hope that you understood my poor english... and I hope that I helped you.
Personally, I'd swap the shifters for some XTR shifters. It won't save tons of weight, but, in my opinion, the XTR shifters have a much nicer feel.
Definately agree on the cassette, easy close to 100g there.
Grips, no brainer.
Carbon bars will probably save over 100G.
Don't forget the seatpost clamp/binder, easy to halve the weight there, although the absolute saving isn't huge, that or the best QR's weigh the same as many basic bolted!
Budget 26" HT build viewtopic.php?f=10&t=110956
These tires are only 310 gram per tyre. it would help to reduce a substantial amount of weight from your bike straight away.
Get Eclipse inner tube for the tube as well. They are only 50 gram each.
Change the seatpost to a carbon one
And get the Sram XX 11-36 cassette
Next should be single ring up front. Should save ~400 g.
Then post, handlebar, cassette, and you can start changing some steel bolts for Ti..
Tires you can go to the S-Works casing.
