Log4J – A 10 step mitigation plan
There are various tools, nicely again enumerated by NCSC-NL at their Github repository with which you can detect whether you are vulnerable. See which one you like best given the situation you are in.
Check what other software you are running and see if the software is vulnerable according to the list published by the NCSC-NL. CISA.gov has a similar registry.

I'm the closest thing to a system administrator at my company, and I don't know anything... what do I do about log4j, if anything?
There are multiple lists of software, the one I use is by the Dutch Cyber Security Center: https://github.com/NCSC-NL/log4shell/tree/main/software Everyday I cross reference on new changes and see if it effects my list. The list can be quite extensive and you might miss the most obvious ones like you FW, switches, SAN or some print software.
