I'm building a bike right now and have purchased a nice Fuji crabon fork. I have my brakes and wheels ready to go, but I'm a little paranoid about overtightening and cracking the fork.
With the brake, should I just tighten it snug and try not to overdo it? Is it even possible to crack the fork-ends by over-tightening my axle nuts (assuming the axle is sized perfectly between the dropouts)?
Or should I just pay the LBS to put these on for me?

Check with the manufacturer regarding the torque on the brake mounting bolts. Get and use a torque wrench when securing carbon components. Inexpensive ones are available from vendors such as Northern Tool or Harbor Freight.
Secure the axle nuts or quick release skewers normally; if you don't tighten them sufficiently and your front wheel comes loose you will have more to worry about than cracked fork dropouts.
