A couple suggestions. The first is something I'll be doing on my next trip to the LHBS. Stuff that is used once or needs to be regularly replaced. Things like hose (for a syphon or whatever), nylon mesh bags, sanitizer, etc. Get some backup stock of things so it's there when you need it.
The second is more for me personally because I don't know your setup. Storage. For a long time I've kept stoppers, airlocks, bags, thermometers, and other things in one big drawer. I've been slowly been rearranging how I have things stored so everything is separated and easier to find.
