Yes. It seems that Zinsser shellac-based primer (BIN) will adhere to just about everything, and even if it takes a few coats, will seal just about everything.
Generally, yes, although the water-based stain may run a small amount after application if the wood still has a lot of oil present in it. After 15 years, it should be okay.
Yes.
You should check the label on the specific product you're planning to use. If the label states it will adhere to wood with an existing coating, then it's fine to use even over an oil-based stain. (This is because once thoroughly dried, oil-based stains behave the same as water-based stains.) Some products, however, will require the existing stain to be stripped from the wood, or to apply a primer coat over the existing finish before applying new stain.
I am doing that right now. It says on the can that it can be applied over an oil based stain...but the stain may continue to "amber" under the coating. I decided to go with the polyacrylic because a friend told me that polyurethane yellows over time. I don't know if that is true...but that is what I decided to do. So far, the acrylic is going over and drying over the oil based stain without any problems.
The best way to stain cabinets is to apply the stain over shellac then shellac over the stain last step Zip Guard over that to protect surface from moisture damage

you only use primer over bare wood or stains. If you have really tough stains you might need to use shellac based primer, otherwise any stain covering primer.
Yes you can if it is a solid stain. However, if you're using toners or semi-transparent stains, you'll want to remove all the water based product prior to applying the oil based stain, otherwise, it will appear blotchy if the water based stain is worn unevenly.
Yes, you can

A coat of shellac can be placed over polyurethane. You should use de-waxed shellac if you plan on placing more polyurethane on in the future.
You can wash it off with a moist sponge, but it is likely going to still leave a stain. Drywall is very porous. It is basically paper over chalk. There is just no way to remove some stains. If you want to paint over, but the wood stain keeps bleeding through, cover the stain with a product like Killz. It sometimes takes a couple of coats. Once the Killz is totally dry, the stain should quit bleeding though. It can then be painted over. Just keep in mind, if you are using a water based paint, use water based Killz. If you are using an oil based paint, use an oil based Killz.
