I would take the equipment for a spin. A few nights, and viewing the results in OSCAR, should tell you what is going on. Then you can replace the parts that might be too far gone or aren't working well for you. You might also find that the machine settings need a bit of adjustment. As for degradation and pathogens, there is nothing to worry about with your Resmed S9.
I bet that the mask is still good, but you may find that you do better with less than a full face mask. Many doctors and DMEs start people on full faced masks, and then wring their hands when the patient gives up on the machine and mask. Plan on doing a bit of shopping on the mask. And bear in mind that the published lifespan of equipment is to increase sales, and has little to do with how long things actually last. And one more comment on the mask: Full faced masks are the devil for leaks (not to mention comfort), and if your leaks (see OSCAR) are over 24L the machine cannot completely produce the prescribed therapy.
I would also recommend getting a copy of your prescription from the people who did your initial study (it's your right to a copy of the prescription). Once you have the prescription you can order anything online (See Supplier List, at the top of every page here). Online suppliers tend to give lip service to prescription requirements; making sales is more important.
You are just beginning, so you have a big learning curve ahead of you. Apneaboard is your main source of information, but poke around everywhere on the net. And for heaven's sake, ask questions. The only stupid question is the question not asked.
