I did ask resident centurion expert robbietunes but i also dont want to continue to bug him with every little detail, he has been very helpful to this point.

1. Your 105 brake calipers should work fine...I used to run 8spd chorus ergo with older shimano 600 brake calipers (600ex era) without a problem.
2. The crankset is a bit trickier. Changing out the rings might work but the spider where the rings sit may be thicker as well which coupled with thinner 10spd rings may have the 10spd chain getting jammed in between the rings when shifting. If you change the crank to a campy one then get a campy compatible bb too. Campy uses ISO specs for their tapers whereas shimano uses JIS specs. While it is possible to mix and match it is not ideal.
3. Have your rear triangle cold set to from 126mm to 130mm and you should be good to go.
On my old road bike I had a full Shimano 600 ex group on it...I put 8spd chorus ergo levers, an 8spd athena rear derailleur, and rear wheel with an 8sp chorus hub and cassette. I left the 600 calipers, front derailleur, and crankset. The bike works great. But I was moving from 6spd to 8spd which is not as big a deal for the crankset as it is to go from 6spd to 10spd.
Good luck.
