Video camera set up idea: yay or nay?

Hey, me and some friends are going to get a new video camera for this winter. We're on a pretty low budget so we're thinking of getting the panasonic pv-gs300. I've pretty much only heard good things from it. I know there are some ever better options out there, but not for this price ($500) to my knowledge. So ya, here's what im thinking of for a setup, tell me what you think.
Camera:
Panasonic pv-gs300

2. 466mm Circular Polarize Glass Filter

So thats what I'm thinking of getting. I'll be using the same case i used for my old camera, seeing as it will work so theres no reason for a new one, and I just need to get a new head for a tripod then i'll basically have everything I need, to my immediate knowledge. If you guys got any suggestions on my set up please tell me.
