Berserking adds 2 fatigue/round, so that's where your golem picked it up, attacking/moving/trampling shouldn't add fatigue to 0 enc units.

As to the rest, it all depends. Usually forting and then buying some non-cap mages on the discount sites you find will be the easiest way to get going, and then move a few of the cap guys over, since you'll only be getting a few high-powered things a turn, most items you'll be making a bunch of are the low-level stuff, so there's no reason to use a cap mage for them in most cases.
