There are too many variables to answer the question. weight will vary slightly by manufacturer, style, and durability. 3 tab shingles come in 20, 25, and 30 year warranty weights. Obviously, the longer the warranty, the heavier (thicker) the shingle. Architectural (shadowbox) shingles which come with 25, 30, 40 year warranties as well as lifetime warranty also all weigh based on thickness.

33' for 3 tab, 25' for architect Actually, most three tab bundles only cover 32 sq feet. And architectural shingles cover about the same (it varies from manufacturer). But architectural shingles have less waste since there's no exact pattern to follow(unlike the slots in three tab shingles). You can save your scrap cut offs if they're 4-5" long. Owens corning shingles allow 4-5" offsets. You just have to be careful of your nail pattern. Oh, about that coverage, some 50yr shingles only cover 25sq feet, but most are 33 sq feet. Basically, one bundle for every sheet of plywood.
Normally 33. But some are 25.
It varies by company & style of shingle. Usually 33 sq. ft. coverage on most three tab shingles.. Designer shingles usually have a 25 sq. ft. coverage. You can go to sites like IKO.com or BP.com Find out what brand of shingles your local building supply store carries & research from there.
Depends on the shingle. Is it a 25 year or fifty year. Asphalt or fiberglass?
25
Yes. They're thicker, which adds weight to the roof--and the heavier a roof is, the better because heavier roofs cut down on wind noise. They also have better warranties; a very good warranty on a three-tab shingle is 25 years, but the cheapest architectural shingle on the market has a 30-year warranty. With the added windload resistance and not all that much higher price, I think they're well worth it.
Multiply the length by the width of one side of a gabled roof and then multiply by the slope (pythagorean theorm; e.g. 9 squared + 12 squared = 15 squared) and double it (two sides to a roof). This suare footage will give you the amount to divide by a bundle of shingles which covers 32 sq. ft.
In general, this is the recommended replacement schedule based mostly on the material used: Composition Shingles: 12-20 years. Asphalt Shingles: 15-30 years. Wood Shingles: 20-25 years.
