I'd recommend a pair of JT goggles(make sure they are thermal lenses i.e. flex 8, spectra etc) for when you play at paintball fields, and then have a pair of ESS or Revision goggles for when you don't need paintball goggles, as they're far nicer to use. I got a pair of Revision goggles for cheap on eBay since the US is liquidating Foliage Green ones.
As far as a mask, I recommend getting a steel mesh mask, like this: http://www.acmgear.com/black-bear-ai...ey-p-1112.html
^ that's the exact one that I have, and it's great.
