1. Looks like the some coolant just got on the outside of the hole and it turns like that. Give the hose a squeeze to see if it's good or not, look for more cracks and that's about it. A good hose will be firm to squeeze, and go back in it's position quickly after you let go, a bad one will feel spongy and be slow to return, or be very hard and not flex.
2. Just some rust, not a big deal.
3. I wouldn't even use a mechanic for that, with the practice I've had I could swap that thing out in 15 minutes on a 04.
4. lol what on earth is that, is it connected to anything or just strapped on?
