Yes, great idea, pack really really light, forget stoves and cooking, get an 2 person ultralight tent. shop rei-outlet you can often get a good deal on something. Here's the one I use now:
http://www.rei.com/outlet/product/767268 - it's not luxury, but me and my 6'3" boyfriend lived in it for 6 weeks, and it only weighs 4 pounds.
give up everything you can in terms of camping luxury, to make the riding nicer. Put the biggest cassette on the bike you can fit with your derailler - I think SHeldon Brown's site says you can use a 30 tooth cassette with a regular road derailler. 27 or 28 for sure.
That's a nice looking rack! If you need <40 pounds of carrying capacity, and don't mind spending a LOT more $, Tubus Fly fits road bikes with a QR accessory, and is very light.

Use the strongest wheels you have.
I guess, with the carbon rear triangle, it would probably be wise to contact the bike manufacturer and/or the rack manufacturer to see if it's a safe setup.
