For the A/C problem, two things: If you haven't, check the temperature control cable to see if it needs adjustment. You can check here for details on it. Super easy procedure. Also, a few here have insulated their A/C lines and have found some positive results.
I, too, thought the Vibes A/C wasn't that competent... And it saw many trips to the shop due to A/C problems but still never was working as good as it could have, or at least as good as I thought it should have.
For the engine noise, yep, been there too. I don't recall too many (if any) complaints with the GT engine, there have been a few complaints of noisy base engines, one of those was on the Vibe I had... I never bothered to get anything done to it, the noise developed at about the same mileage you have now and was still there at 74K when I traded. Sounding like a diesel pretty much sums it up. I could have had it fixed for the low, low price of $499 or something though (IIRC) so I decided it wasn't worth it. The procedure is pretty involved for getting the valve clearance back in spec if it is out of whack.
Hope you can get everything resolved soon!

I'll second that! Check the Temp control cable in the Passneger side foot well.
And please insulate the large A/C line in the engine bay with the foam pipe insulation. Any hardware store should carry it and most is protected by a fire retardant just in case.
I noticed at least a several degree deference after perfoming this simple, and very inexpensive mod. more Here: http://forums.genvibe.com/zerothread?id=4914
about halfway down the first page i have pictures showing what i did and a little further down the first page i show actual measured results.
Sorry I can not provide any help with the Valve issues are having just dont know enough about them. I would probably just take it to a Dealer. Unless the experts chime in with a better solution.
If it goes back to the dealer, see if they will show you the car hooked up to the AC recovery/charging machine. The machine will show the actual pressure of the system and there should be a sticker under the hood for what the systems pressure should be too. I have not looked so I am not certain but there usually is.
Also, make sure your inside cabin filter is clean and good if not new...
I just hope the noise is not your compressor going south!
