Yes, you can use Kilz over drywall. It is an undercoat, or primer.
You can paint over wall paper. However it is recommended that you prime with an oil based primer. Kilz Original for example. Most wall papers use water based glues for adhesion. If you put a waterbased topcoat over the the wallpaper it could penetrate the wall paper and cause the glue to release. You can use a waterbased top coat such as Kilz Casual Colors over the top of the oil based primer.
tar paper is not a good vapor barrier for the interior. 6 mill plastic is best to use under drywall in cold climates.
You will use an oil base primer to prevent moisture from getting in.
If you use a quality primer like Kilz or Bullseye, you should be OK.
No, it will weather quickly though, except that Kilz does not have a good all-round reputation anyway.

No, it will almost certainly loosen the wallpaper.
To effectively use paper drywall tape for your project, first apply a thin layer of joint compound to the seam in the drywall. Next, press the paper tape into the compound and smooth it out with a drywall knife. Apply a second layer of compound over the tape, feathering the edges to blend with the surrounding wall. Allow it to dry completely before sanding and painting.

Not and have it stay. Start by sanding the ceiling. make all necessary repairs to cracks, water damage etc. Prime the ceiling with a top quality high hiding primer... if you have water damage be sure to use a non-water based primer, I use Kilz (not kilz 2) with great results. Ten use a Kitchen/bathroom specific paint as your top coat.
Yes, you can tile over drywall as long as the drywall is in good condition and properly prepared. It is important to use the right adhesive and grout for tiling over drywall to ensure a strong and durable installation.
To cut drywall effectively and accurately, use a sharp utility knife to score the drywall along a straightedge. Then, snap the drywall along the scored line. Finally, use the utility knife to cut through the paper backing on the other side of the drywall.

To apply drywall paper tape effectively, first, cut the tape to the desired length. Next, press the tape onto the joint between the drywall sheets, ensuring it is flat and smooth. Use a drywall knife to apply joint compound over the tape, feathering the edges for a seamless finish. Allow the compound to dry before sanding and applying additional coats as needed.
I would use Kilz latex primer.
