Hi Lyndell,
As one of the Co-Chairs of the Integrated Pest Management Working Group, which created and manages the Museumpest.net website and the free PestList listserv, your query raises an excellent point as we don't directly address post-infestation cleanup on the site. That is something we can work on adding at our upcoming meeting in mid-March.
But to address your immediate need I have a few questions for you. What is the current cabinet made out of? Is it wood with wood drawers or metal? If the cabinet drawers are wood I'd recommend freezing them along with the taxidermy. If they are metal then a good vacuuming and a wipe-down with isopropyl alcohol would be appropriate. As Beth mentioned, a vacuum with HEPA filtration is a good idea for these nasty projects. Having a set of micro-attachments like these is also helpful (note that there are different kits depending on your vacuum nozzle size)

As for how long to let it sit before using it again, please let us know a bit more about the cabinet or send some pictures to the list!
Book lice require humid conditions. In addition to the low-temperature treatments, bringing down the humidity in that area of storage will inhibit their activity and reproduction. Unfortunately cigarette beetles are extremely damaging and harder to kill. It is great that you are trapping in the cabinet. I would recommend placing a grid of traps outside as well to determine if there is any chance the infestation spread beyond the cabinet. Also, a few comments about pheromone lures. They can be very useful in determining the presence and extent of a problem, but they must be used properly. We have some info on pheromone lure tips on our website
Monitoring - Pheromone Tips
They are species specific and I don't believe that there is one for either Cigarette or the Drugstore beetle. Insects Limited has a good bit of useful information on their website about the best traps for these species.
https://www.insectslimited.com/museum We have an outline of freezing protocols on the website as well.
http://museumpests.net/solutions/The important elements are wrapping your collections in plastic to avoid any damage from condensation when the treatment is over and the pieces come back to room temperature, and finding the right balance between duration and temperature. Your freezer must be capable of getting below -20 degrees Fahrenheit.
This is also a good opportunity to let everyone know that there will be an IPM Workshop geared towards museums, historic houses and library/archive collections held at the Insects Limited labs/offices in Indiana this coming March. Registration info is available on the museumpests.net blog page

Best,
