Station skills are the ones that aren't utility or tool skills - the exact name depends on the craft, of course.
I spent most of yesterday doing batch work orders (VE to Moderate) with my little artificer, and taking notes on the events & results. Not much to report about that yet, but I did decide to "even out" all 3 of the skills in each category (refining/finishing) and so far it hasn't done any visible harm. She's only level 8 now though - low-diff work orders don't give much xp.
