It's actually a diuretic, which is the oposite of hydration. Coffee is a gourmet food and caffeine is way better than alcoholic beverages, but for biking it would be better to restore glycogen. Get out the sugar!
1) Dosage is not terribly impotant with caffeine.
2) It's not a powerful diuretic.
3) Both are good. After 2 or 3 hours in the saddle I love something cold and preferably mocha. A mocha Starbucks Frappucino is good. But something richer is tastier. ANyway, the point is, coffee is great stuff, cyclists take to it as naturally as babies to mother's milk. Always have.
