If I can offer any advice, it is this....
If you going to build yourself a bike based around a carbon frame with other carbon parts, a good torque wrench is an absolute MUST. You simply cannot afford to over-tighten any of the bolts/fixings as the result could be catastrophic.
I have recently built a Scott Foil and found it hugely satisfying. You will gain an in-depth knowledge of the bike and how it works and will potentially save a small fortune on servicing costs, as you will be able to do it all yourself.
There are some "specialist" tools that you may need along the way, but these don't need to be expensive. I found Planet X a good source for cheap tools.
