I am in the same boat. So I used the Bobster goggles recommended in other threads here and I am going with those again, you just have to decorate/cover the three small airholes on either side.

For the mask, I am going with a combo of one of these wrap bandanas for lower dust times since I wanted to do away with having to tie a shemagh or bandana. And then I am trying out this Aria Dust Mask in addition to the wrap for high dust times. It has a super small foldup profile and a very small metal nose thing (like smaller then size of two tic tacs end to end) with a comfy rubber buffer. And it slips gently around your ears instead of the back of your head.
