Cam lobe wear, and 2 mystery leaks - can you help me?

[Will_w202]

I changed the oil today and decided to take some pics. I have eraser tip-sized droplets on my garage floor since the last oil change 5k ago. I also have buildup and a separate leak from the power steering pump coolant line (I believe). I took pics, maybe you can help me identify what these lines are and where the issue might lie?

Car is a 97 C230 with 108k. Every seal, even the head gasket, was replaced at 80k under Starmark.

I am going to attempt to attach pics.......

The PS line is gooier than it looks - I cleaned it off last oil change and it's sludged up and oozing again. The other "mystery" line is behind the oil filter housing and should be obvious. There is oil seepage coating the mystery line, and based on where the oil dropped to the undercarriage tray and then on to the floor, it appears to be riding down this line.
