Like others have said... for actual specific equipment hire a consultant.
Here are some things that I have found "missing" from new theaters I've worked at. (and some older theaters that just don't know quite what they are doing).
Plenty of:
Black
Gaff (5-10 rolls)
White
Gaff (2-3 rolls)
Spike Tape of multiple colors both subtle and vibrant (at least 4 different colors)
Glow tape (2 rolls)
Sand Bags (well you will have extra pig weights...)
Line Locks (2+ always by the
rail)
(plus proper training on
Counterweight rigging systems as they are quite dangerous, even if you already have been trained you might consider getting refreshed).
Some clips for holding up the spreader plates while you are working on loading weights.
Good quality rope at good lengths for other hauling and or rope needs.
A good way to organize
gel + gobos. I recently saw a rolling lighting expendables cabinet that I really liked.It had 7 or 8 drawers for
cyc sized cuts and for full sheets large enough for any company's size and about 2" high per drawer. An
flat area on top that was at a good working height. A small side drawer for pencils / clips / other marking devices /
scissors /
etc. 3 file boxes which fit on top for cut pieces in hanging file folders, and 3 or 4 drawers were down the side that fit
gobo's in small envelopes.
Depending if you are getting all new gear or all old gear,
purchase a repair kit (if old gear definitely, if new gear you can hold off on this until later).
That would include extra plugs for your
system (
stagepin,
edison, or
twistlock depending).
Crimps
Crimper tool /
Wire Stripper
Multi-meter
E-tape
Search up on this website some good books for reading and reference.
A good set of rules.
My favorites from past theaters are:
No Eating in the theater / on
stage / dressing rooms.
No Gum. Anywhere. At any time.
No Popcorn.
No
Duct tape (
Gaff Only).
Only have drama on
stage
5 minutes early is on time, on time is late (okay so if you have a class period on time is on time...)
It would help to know what kind of stuff you are doing and if you plan on teaching.
if you are teaching technical theater, you'll probably want to get enough c-wrenchs for what you are teaching in regards to lighting.
As well as a pretty outfitted scene shop with all the various saws, drills, clamps, and other carpenter-ie things. (note: i'm a lighting guy, not exactly sure what you will need there).
Probably some gloves and flash lights for student crews to use.
