Is the trim stained wood with a poly coat over it? If so, then you will want to sand it down first, just enough to rough it up a bit. Wash it down with mineral spirits and remove any "foreign matter." Then prime it with something like Kilz or BIN. Personally I like the Zinsser 1-2-3 primer myself.
Not sure what to suggest there....Kilz is a good primer but it's runny and you're not wanting to get it on the paneling. You might want to use Zinser Coverstain which maybe what Dan meant as it's thick but you might have to do 2 coats to prevent bleed through. The 1-2-3 product is awesome but a latex product and won't block any bleed through. Is it a stained wood molding or the plastic type? Just tape off the paneling to catch the drips.
Vania, the only thing I would add to Dan's advice would be that, after you sand, wipe down the trim with something other that mineral spirits or paint thinner. Paint thinner does not evaporate cleanly, It leaves an oily residue that will keep (especially) latex primers from adhering their best. This may not matter on the crown molding but more so on lower areas that get bumped around. The tradeoff is, that the solvents cleaners that leave no oily residue, are a little harsher to use.

These are solvents like deglosser or Naptha, available at your local paint store or The Depot. Any time you are cleaning with any solvent you should wear a respirator and chemically resistant gloves. You can buy these in less expensive, disposal models. Also, arrange some flow through ventilation.
All this may sound a little daunting but if you don't prepare properly, you can easily end up with chipping paint that will not be remedied.
After all is painted, think about wiping over the painted trim with a glaze that will make it compliment the paneling.
What existing coverage? I thought the trim is currently stained...if so, she needs to prime first and she should be using an oil-based primer not latex. After that oil primer....paint with latex all you want!
I renovated a house with an ugly cheap '70s paneled back room.....TRANSFORMED it by adding chair railing and deeper baseboard, painting the paneling and moldings from the railing down satin creamy white. I wallpapered over the paneling above using that textured wall covering that Lowe's sells in a grasscloth pattern. It's thick and hides all the paneling lines! It was STUNNING!!! Total transformation!
Only thing with Kilz is that's it's runny and she's only planning to do the trim...Coverstain is thicker and I've never had any bleed-thru with it. Tessa....pics?
Nice job Tessa....so you used the "new" paper over the top half of the panel? Post a before if you have one. You could also add a piece of picture mold maybe 2" below the crown to give it a built up crown look if you paint all of it...the new trim, the wall in between and the crown white. I've also added that 2nd piece of trim and left the "in between" wall it's original color....looks pretty cool...have to post a pic.

I've primed and painted a bunch of paneled dens and family rooms for clients with Duron "Ozark Green"...name stinks but the green is awesome. I used it in one of my own homes as well..
Yes HandyAndy, that paper is GREAT!!! I also tiled over the brick steps, so it all got covered. The before pix are still in my camera I think! It's really dramatic. Thought about that picture rail, just not good at cutting that stuff! I was flipping to sell. Sold it, and they foreclosed on it ......all my hard work is just sitting there boarded up!!!! But I learned a lot!
