Probably the only place you'd enounter p24 content is with movies on DVD. Ironically, all movies are put on DVDs, HD-DVDs, and BR DVDs at 24fps, but the DVD players use the flags on the disc to interlace the frames into fields (for old TVs like mine) ,and to do the inverse 2:3 pulldown (to convert the display to 30fps) as needed. As more TVs get the ability to handle p24 video, more players will come with the ability to output it, since they don't have to do much more in the way of processing (in fact, they'd have to do less), and the output would look much better because they don't have to employ creative processing techniques that compromise the quality of the material.
The Toshiba HD-XA2 and HD-A20 are supposed to have firmware updates that allow it to output p24. Most of the new BR players output p24 as well. I haven't been following them as much because I'm in the market for a TV right now. You know your player can do it if you have a "movie", or "24 fps" output option in your player's setup menu.
All the other components that are feeding video to your TV are probably p30 or p60, so 120Hz won't really do anything for you. So I guess, if you don't watch a lot of movies and aren't willing to buy a player that can output p24, I wouldn't worry too much about a 120Hz capable TV.
