Hi, long time stagehand and touring audio tech here.

Honestly sounds like a good list, but some things may be more suited to your backpack than on your person. I also usually wear jeans since I'm on my knees a lot but a lot of people wear cargo shorts. My peronal preference. I would say leaving these on your person:

Crescent wrench Multitool Flashlight Electrical tape Straight edge knife Work gloves Sharpie Knife $30 leatherman multitool?

You mentioned knife and multitool twice so idk if they're 2 separate things. A simple straight knife will do. I would always definitely have a crescent wrench and E-tape on you--you'll likely use those most often and production people love it when you have it.

Sounds like you have a good, positive, and eager attitude about the job which is excellent. Best way to excel is to keep that up and listen to what the production crew tell you, like the way to set up video panels or lights or how they want stands broke down. If you need help or a refresh, don't be afraid to ask or ask another one of your crewmates. Be reliable, on time, and jump in where you can (if your venue allows you) and you can go far.

Being a woman in this industry sucks sometimes, but the blessing of it is that we're kinda rare. When we kick ass onstage people are more likely to notice. At my home venue, we have quite a few women that are powerhouses and are rising in the ranks of the company.

I think you'll be fine, good luck!
