Professional modellers recommend 4 layers. I usually do 2. One base, and the other the actual color.

Depends on the model actually, but I tend to join up pieces first which have to look even, such as the arms or thighs.

Anything goes, but I usually buy the official Tamiya or Mr. Hobby colors.

Air brush, fine markers for details. Check out a dummies' guide I did a few years ago.

Adhesive.
