PS3 glasses will not work, but the glasses that come with the monitor will work with the monitor, and I do believe the PS3 as well.
Make sure the glasses are charged.
You need to go into the Nvidia control panel, go to the 3D vision page, and run the wizard to get it setup. Once setup there, it'll be available in game, but not all games work well with 3D Vision. For some of those games, go here for a fix: http://helixmod.wikispot.org/gamelist
It is mandatory that you run the monitor through a dual link DVI cable.
