In short YES and YES.
There's really no simpler answer. But it doesn't help you very much
Your room/ set up/ screen size / throw distance and viewing angle will also impact regular and 3d viewing. Each set up will not yield the same results with the same glasses and screen.
Now having said that, there are better glasses than others and price is not the best indicator of such quality.
I have 2 pairs very similar to those that Willshire posted and I'm quite happy with them. They are no name glasses and work quite well, there are dedicated thread for the best 3d glasses here on AVS and other forums as well and I strongly suggest you go trough them first. On my part I bought the cheap ones where I bought my PJ so I did tried them on first. Either find local, or a good return policy. I would also suggest that you try One pair before ordering 6 of the same model solely based on comments.
EDIT: all full hd 3d certfied will work with the epson.
Screens well that a very different mather and it might even be more complicated than the glasses especially if you want to keep watching 3d. start by reading (or searching) this whole thread if you have not yet. you will probably find answers to your questions. then it all depends AGAIN on YOUR set up. living room or bat cave etc etc.
Audio and Video are really subjective and the result vary immensely from one setup/location/individual to another.
It's really hard to give better advice based on the few details you gave.
