What are the major sources of cabin noise in cars?

I've been thinking of buying noise dampening products to make my car interior quieter. It seems that the common approaches are to get spray-on dampener for the wheel wells and peel/stick sheets for areas like the trunk. Some people go nuts and tear the entire car apart to line the entire cabin with sheets.
I don't have time or money to go nuts, but I would be willing to be a little crazy to target the top 3 or 4 sources of cabin noise, if I could figure out what they are.

My guess is that the list would look something like this, but I'm hoping someone can point me to some actual research on this.
1. Engine vibrations coming from everywhere
2. Wind noise coming in everywhere (especially doors?)
3. Tires on the road noise coming through wheel well
4. Transmission noise coming through floorboard
5. Road noise from trunk and floorboards
If I knew for sure that one area is a major culprit, I'd totally be willing to (e.g.) disassemble a door and dampen the inside, but I'm not going to go through that effort on a guess or just go nuts and dampen everything.
