As far as the sleep apnea machine they are amazing. Started using one about a year ago... I use a Elan Sleepweaver cloth mask. And for me that has been super comfortable and very easy (since it's a soft type mask)
It's going to be very awkward at first... and takes some getting used to.. but once your used to it you will have really good sleep again.
Look very very closely at what your insurance company will pay vs what you will have out of pocket....
compare that to what you can just purchase a machine outright for from somewhere like CPAP.com. Because of the high humidity here in LA i almost never use my humidifier for my machine. So consider just purchasing a machine without humidifier.
If i had to do it over again, i would not have let my insurance company talk me into the BS deal that they did for their overpriced cpap machine. By the time i pay my yearly deductible I end up having paid 3x what i could have bought a brand new machine for, and then because it was a rental rather than a purchase.. you get to do it all over again for every year.... I said adios to them after realizing how big of a scam it was.. and outright purchased machine 6 months ago.
If budget is real tight you can get a refurbished unit from somewhere like
http://www.secondwindcpap.com/ (your gonna get a new tube and mask anyway so it's not like a refurbished machine is a bad thing)
after you start using it... Welcome back to real sleep... amazing difference.
