Probably just soot from the engine. Not really a pretty sight. I'm sure it can be easily wiped/washed off. I'm quite sure someone here can give you a better answer.

You are said to be a good pilot when your take-off's equal your landings.

Looks like APU exhaust, you can see the outlet by the registration.

Thats where the APU exhaust blows on the side of the right engine... this is visible on DC-9's, too.
The APU exhaust port is the little hole on the fusalage next to the right engine pylon.

It is just soot, probably from the APU, as others have stated.
But.......Its not easily wiped/washed off. And when you get it on your skin, you might as well just wear off a layer of skin. It does not want to come off, no matter what you try. My wife is always accusing me off not washing my hands. Yeah i just spent 1/2 hour taking a layer of skin off with a brilo pad, but I didn't wash my hands.

If the cowling is open while the apu is running the exhaust is hot enough to burn through the cowling. All DC-9 and MD-80's look like this. The soot never comes off.

What are the vertical black lines in the triangluar pattern on the wings and the tailcone for?
Shall I assume the arrows on the wing are for where to exit?

The normal escape path from the over wing emergency exits on the DC-9 family of aircraft is to head to the rear of the wings and slide down the flaps, which would be extended to the ground, that's why the arrows point to the rear.
To prevent the exhaust soot from being embedded in your skin, there is a product on the market called ProTec, also known as "Invisible Glove". It comes in a tube like toothpaste and you should be able to get it in hardware or auto parts stores.
It seals the pores of the skin and is water soluble. It comes off when you wash your hands. Almost all the soot will wash off with a good hand cleaner or Java hand soap, it tends to dry the skin so you will need to use a good skin cream after washing your hands. I used it when working in jet exhaust areas and it helped a lot, also is great when working on car engines.

The black lines on the wing are an anti skid strip. The black lines on the tail cone are not on the tail cone. They are louvered vents just forward of the removable cone. They vent the unpressurized aft section.
