I've never done that play, but there are some ways to help deal with a heavy-prop show. Not knowing very much about where you are in the process or what exactly you're having trouble with, here's what I would suggest.
Create an organized, coherent props list. It may be that your director or even the props person has already done this, but it may benefit you to keep your own list with the information that you need on it. Confer with the director and props person when making this list, and keep the props person up to date on any changes made during rehearsal.
For a large prop show, I like to number the props so that when you refer to them in the report, it's clear exactly which prop you're talking about. (i.e. Sarah's bag(#34) should have a false bottom). If there are 8 chairs that all look the same, give them each a separate number. You can label them with masking tape in rehearsal for easy reference.
Keeping your own list allows you to track something like whether or not you've received a rehearsal stand-in for each prop- it's easy to glance down the list and see which props don't have a check mark in that column. Or you can track how many of a consumable item is needed for each show, etc etc. Updating the list daily will help eliminate confusion. If you cut a prop, don't reassign the number- that way it's a lot easier to restore the prop if needed.
Start making a prop preset list on the first day of rehearsals, and use it every time you set props. Don't rely on your memory- if you use the list every time you set, you won't miss anything, and you'll notice errors on your paperwork sooner.
If you have an ASM, you might consider assigning them the responsibility of tracking props. If you do, make sure that they are keeping their paperwork up to date, and that you have a copy.
With weapons, it's important that the cast understands that weapons aren't toys- even stage weapons can be dangerous. They should be carefully tracked and locked up at the end of every night.
Is there anything specific you're concerned with?
