Question Whining Noise, Damp Bolts by Radiator and A/C Valve and Unknown "Drainage" hole?

In this first image, I was just wondering what this is lol... how to clean it properly and some dirt and gunk has falling in and will it be ok? I suspected it is just a drain for the windshield water from rain fall to wash away and drain out the body towards the bottom.

In these next two images, I noticed the entire engine is dry but these two area are wet. This image you can clearly see where it is wet, near the radiator cap.

Now in this image it's harder to tell but the obvious black bolt there and that assembly is wet. I don't see any obvious leakage but an occasional (5 minutes or so) drip from it.

Lastly I am hearing a slight whining noise when accelerating that makes me think it may be a belt, thinking it might be the timing belt. Way too difficult a task for me to do but just wondering if there would be any peculiar behavior associated with a bad timing belt. The whining doesn't always happen, seems to be only when accelerating and noticeably dies down when coming to a slow stop.

I know this is a lot to ask in just one thread but I didn't think adding a bunch of entries was a good idea either.
