1. No you cannot use your old stereo emitter. The 3D Vision Emitter is required for stereo on 120 Hz LCD monitors. You will also need new shutter glasses from Nvidia, but these some with the emitter. I'm not sure the reason, but I'd guess that the older emitter can't transmit the signal at the correct frequency to get 60 Hz to each eye.
On a side note, consider which operating system you are running on the system to be used for stereo. You'll need the 3-pin stereo connector if you want to do stereo in Linux. For Windows it isn't required. Some computers that Dell and other manufacturers sell with FX3800 cards don't have one built in, and you will need to buy an adapter that hooks into the video card to provide the port. 2. The normal "3D Vision" system uses IR signals to communicate between the emitter and the shutter glasses. "3D Vision Pro" uses RF signals for communication between the glasses and the emitter and has a longer range and doesn't require line-of-sight like the IR system (hence the hefty price difference you've noticed). I don't believe the glasses from the normal "3D Vision" kit are compatible with the "3D Vision Pro" system due to the difference in signaling systems, but I haven't tested this. If you're going to be sitting in front of a monitor doing modeling and don't have alot of IR interference in the same room, the normal "3D Vision" version will suffice for your needs. "3D Vision Pro" is more geared toward having large meeting rooms and presentation halls equipped so everyone in the room can view 3D on a large screen driven by a 120 Hz DLP projector. 3. I don't wear prescription eye glasses, but I do have long modeling sessions without any discomfort wearing these. They come with several inter-changable nose-pieces so you can pick the one that fits you most comfortably.
