Yes, however clear polyurethane has a yellow cast that will affect the color of the paint. Most water based clears are crystal clear, very durable and can be used in place of an oil-based clear coating.

Yes, Olympic, along with other manufacturers, make a water based poly that can go over a water based paint. The label and data sheets do not say painted specifically on some of these products, but as long as they say they can be used over a sealed surface, then it will work fine.

The benefit of using water-based instead of oil-based poly is that water-based is crystal clear, instead of yellow like the oil product.

Yes, the poly does not soak into the wood, for the most part, so it can be put on any stain/paint. I just put it over Behr Weatherproofing stain last week.
