I've no idea what I'd be doing with a touch pad in a game, so it mostly sounds like something new for the sake of it. Sixaxis at least did have good uses in a number of games and one could envisage how such functionality could be used. One advantage over the WiiU is that every controller will have it, not just one per console.

Slightly bigger controller, fine but personally I don't need a bigger controller.

Change L2 and R2, yes definitely needed.

Very few in game uses aside from swiping and pressing. Thing the touchscreen use on the Vita for games like the upcoming Killzone. Slashing to knife. Or how about for the occasional wall smashing to push down on the touchpad instead of pushing X or O or whatever. Maybe if the PS4 comes with a camera and the controller acutally has those LEDs on the front, it could do things like the ninja throwing star on the Wii U. So maybe you could aim grenades by holding down the touchpad and moving the controller to change what angle you are throwing it at, which might be pretty effect compared to a lot of FPS that have you look off into the sky and guess how you are throwing it.
