Paint advice

Bought crappy old house, in process of making it less crappy before we move in.

The lovely textured ceiling has yellowed and the room is stinky. I removed a cabinet off of the roof and you can see how bad the yellowing is.

I'm not sure how to describe the smell. I don't think it is from smoking, probably more so decades of cooking without any ventilation (and total lack of interest in ones living environment.)

What am I best to do to deal with this before painting it? Is that textured crap likely to have asbestos in it?
