Bottom brackets are pretty easy. Headsets are pretty simple too, but you're better off having the cups installed by a pro. That is unless you wanna purchase a headset press. I've heard of all sorts of methods for homebrew headset presses, but my personal preference is the right tool for the job.
Alas, a Park headset press goes for somewhere in the neighborhood of $200 to $300 (Though I noticed Nashbar has theirs on sale now for $80.) so chances are you'll be making a trip to the LBS. While you're at it, if it hasn't already been done, have them face the bottom bracket (Requires another *really* expensive tool that most home mechanics aren't going to have.) and chase the threads (ditto), to get it ready for you to install the bottom bracket.
Have fun!
