For the Mac Book I think you need to use the Mini DVI to video adapter (store.apple.com) and then connect either an s-video cable (or yellow video out chord) to your tv. If you want to also connect audio you'll probably need something like a stereo to RCA cable (radioshack.com). My G4 Powerbook has built in s-video output, so I usually just connect an s-video cable to the tv and a splitter similar to the one above plugged into the headphone jack. The System Prefs make the whole thing pretty simple really. Good luck! :]

For Palm OS I think you want Palm Desktop with Hotsync. I've never used it, but looks to be able to do what you're planning. Grab it while it's still on the Palm site as it appears certain KB pages are getting phased out. More details + download link:
