What is the prep work and what kind of primer is needed to paint over wood paneling in a bathroom? Part of this old bathroom has wallpaper. What is the best way to get all of this off before painting? Help me fix this old and ugly bathroom!

What's old will soon be new again!
FIRST REMOVE WALLPAPER:
Wallpaper is held in place with water-based adhesive. Removal is a relatively simple, although tedious process of re-wetting that adhesive and then scraping off the old paper.
I recommend the DIF Wallpaper Removal Kit ... most commonly sold as individual items at The Store.
The concentrate is mixed with warm water to help it penetrate the paper.
Multiple wettings (3 applications about 5-minute apart) will penetrate the paper ensuring it releases easily from the wall.
Most DIYers are familiar with the PaperTiger, however I DO NOT recommend using this tool unless multiple wettings will not make the paper release.
WHY? Because this tool also scores the wallboard behind the paper and create a secondary repair ... skim coating the wall with sheetrock mud and sanding the surface to return the wall to a smooth surface.
So, try the multiple wetting using the warm concentrate, one wall at a time, first!
The blunt-tip blade of the Paper Scraper is another very good tool to help remove wallpaper. Unlike sharp-tip paint scraper blades, which often destroy the surface of your wallboard, the blunt-tip tends to glide along the surface to remove wallpaper without creating additional damage to the wall.
Once the paper is removed, clean the surface with warm water on a sponge.
SECOND PRIME EVERYTHING:
As luck would have it, you need oil-based primer to seal both the wallboard after removing paper and the old paneling.
I like Zinsser Cover Stain.
Cover Stain derives its name as the base coat for covering stained trim, cabinets, and paneling.
According to the manufacturer, Cover Stain "Sticks to all surfaces without sanding. Dries Quickly" (about an hour). And allows you to "Use any topcoat."
Cover Stain is also the right product to prime and seal the water-based wallpaper adhesive ... which has been known to bleed back through water-based primer and/or paint.
TINT YOUR PRIMER:
Cover Stain is tintable and there is no charge for tinting, so ask your Paint Associate to make your primer similar to your new color. You'll be adding your first coat of color while you primer.
REPAIR THE WALL:
During removal of wallpaper there is usually some damage to the wallboard. Use sheetrock mud and a wide-blade mud trowel to fill the damaged areas. Allow the repair to dry, and then sand lightly to smooth the walls.
Use your hand to feel when the repair is smooth or a light shown down the wall to see when the repair is smooth.
When satisfied with your repair, re-prime the repair areas.
Once the primer dries, you're ready to paint.
In a bathroom, I prefer a washable flat, eggshell or a satin sheen. Washable flat (Flat Enamel) is the least shiny, but is also the least washable. Eggshell is slightly shiny, and is considered wipeable. Satin is shinier and is washable.
Keep in mind that shiny walls reflect light and thus show more of the imperfections.
Most of my customers choose washable flat or eggshell after removing wallpaper.
I love projects like this!
You're re-claiming a space that has only been OK and turning it into personal space that you'll love.
Consider repainting your trim before completing the walls to really give your new space a fresh, clean appearance.
