Issue 1, let us imagine that I give the engine the full beans in neutral and let off. As the revs fall past 2k, there's a ratcheting noise from the engine bay that lasts about half a second. Issue 2, she chirps. Under certain load, usually 2.5-3.5k in 3rd (auto, mind you) I can hear a chirping, it sounds like something just seriously wobbling. I'm thinking both of these are pulley or belt related. Timing belt hasn't been changed to my knowledge, car is at 95k and change. Dissection, criticism and help greatly appreciated. Thanks guys.

Fair enough. I was hoping somebody would chime in recognizing it as a common noise. Well, I'll be doing brake work within the next few weeks, so I'll check things over with my buddy. Bearings, belts, pulleys, might as well take the timing cover off and see what the story is there.
Does it help if I say that the chirp occurs only with load on the car, such as holding the car at a stop when idling in drive, or accelerating in light loads like I mentioned?
