I think you and I probably represent the majority of the vets on this forum, but with new people registering everyday, perhaps we won't be so alone for long.
As much as I hate to say it, the best way to get the VA moving is to keep pushing at them. Since you had the test and they determined that you had apnea, you should probably talk with your primary care doc and see if he/she can push them a little faster. If you let yourself go with the flow with the VA, you most likely will end up drowning in the system, or at least that's my experience with them. You might also want to check into getting your primary care to refer you to an eye clinic for glaucoma screening while you have them on the phone since apnea can contribute to non-age related glaucoma according to a small Mayo Clinic study done at the Jacksonville, FL clinic. Sometimes it takes weeks to get an eye clinic appointment, at least at my clinic. Also, you might want to contact prosthetics, if you have that department at yours, and see if you can gently move them along faster, if you are getting your equipment directly from the VA. If it is going to be Fee Basis-ed out to a local DME, then you need to contact Fee Basis (yup, that's what they call the department that deals with outside the system payments) and see if they can move things along. Good luck with the VA and I hope they get your cpap treatment going before much longer.
