Where are you? The NY Metro area??
Go to the NY Public Library Annex on 5th Avenue between 40th & 41st Steets. I think the periodical circulation desk is on the 2nd floor. Go to the window and ask for the current issue of ARTSEARCH.
This is a monthly newsletter-ish kind of thing published by TCG (who also publish American Theatre Magazine) that lists jobs at regional (LORT) theatres across the US.
It is worth a look-see just to find out the jobs that are being filled and where.
If getting to the midtown is not easy or if you (or anyone reading this post) are not near NY at all, other libraries such as at a large college or university may carry it as well. Call around. Subscriptions to this are not cheap so find it in a library rather than buy it.
Look at www.tcg.org for all sorts of info.
In general, the more you know, the more you know.
Can you balance a checkbook?
Know how to leave a paper trail?
Remember obscurities or at least where you or somebody else put these obscurities?
Do you give good phone?
And then there are various computer program skills.
Do you know all sorts of terminology? Like any industry, theatre has its own slang.
As gross as any of these may sound, they can help you get a job.
Have fun.
