more questions about my build

1st;
when i slide the race over the fork crown, it stops about 1/4" from the bottom of the crown. before i try to seat it, is this typical or does it sound like i should have the crown machined like shown on the park tool website?

b;
i have a rather diverse set of components to pick from. i'm considering swapping the components on my regular bike with sram force derailleurs and rival brifters on shimano gears (std dbl 10spd). will this combo work ok? i was talking to a tech at a shop and he said the only issues he had heard of was using an fsa crankset with shimano derailleurs (i forgot which "level" of components he said).

lastly;
on my build, i may go with a chorus compact crank with an ultegra cassette and 105 dr's. any issues with this combo? can you mix shimano and campy gears?

It is normal for the crown race to fit tightly like that, it should tap down the rest of the way fairly easily with a race setter. You should have to tap it with a mallet to get it all the way down. If it seems like it is taking to much force to get it all the way down it could be too tight but this is usually not the case. Just make sure you use a proper race setter to put it on and it should be fine.
shouldn't be a problem to use the Campy crankset. Using shimano derailluers with a campy cassette would not be a good idea but the crankset shouldn't matter.

you need to set the crown race, use a piece of pvc to bang it on. or use a screwdriver http://www.youtube.com/watch?v=z0FaQy07t80

If it takes a lot of force to slide that lower race on you may need to face the crown. But, as the others said, it's suppose to be tight. When I built up my Colnago it was necessary to have the fork crown faced before the lower race (Chris King) could be installed. It really depends on your particular components.

I think if your SRAM shifters and SRAM derailleurs are compatible (cable pull and throw ratio) you will be fine with the Shimano drive train.

A Campy standard crankset will work fine with an otherwise Shimano drivetrain. But you may need to find a front derailleur that best matches your chainring sizes. You could try the standard 105 but it may not be best. I don't have a compact yet but when I buy one it will have 50/36 chainrings instead of the more common 50/34. The closer ratio spacing should be less trouble, and in my opinion the 36 should be more usable than the 34. But if you need the 34 then you need it.
