When talking about the area of a roof, remember that it is not the same as the square footage of the structure. For example a 20 x 30' building with a 12" overhang and a 4/12 pitch will have 736 sq ft of roof vs only 600 sq ft of slab. One square of shingles covers 100 square feet. 15 year shingles come 3 bundles to a square. 25 year come 4 bundles to a square. The ridge vent will vary with each job. They are 4' each.
Rake overhangs are not as critical to vent as are the rafter spaces above the living areas, but for the sake of appearance, the entire ridge is usually covered with venting.
