GRS 8PF-8 8" Paper Cone Foam Surround Woofer
are the grs-8PF-8 8 inch speakers good for a small pa speaker replacement
Probably not. PA and musical instrument speakers have a higher SPL rating than home audio speakers such as the GRS. This means that it will not play nearly as loud as the original speaker, possibly making the high frequency speaker sound over-bearing. Not what you want! Go with a pro-audio type woofer.

How would this woofer perform as mid duty? I have a 12" goldwood woofer that I was planning on using for the lows and I have a few of these sitting around and was wondering if they would work.
Usually an 8" speaker will only play conservatively up to about 2,000 Hz before it starts to beam. If you pick a tweeter that will safely cross this low it should not be a problem.

Would these work in an open baffle situation? The q values tell me it would, and Im not very concerned with the Xmax because they'll be used with a bandpass
Yes these will work for an open baffle application.

Could these work in a 2-way system
I would like to build some budget speakers for my garage and I was wondering if these would work in a woofer/tweeter type system, if so, what would be the x-over point for the tweeter?
These could work as a two way assuming your tweeter can cross over low enough. I cannot recommend a crossover point without knowing which tweeter you plan on using.

How about 2 per 1.77 cu.ft. sealed enclosure?
My woofer airspace is 1.77 cu.ft. Sealed box not including the woofers themselves or "stuffing".I Was considering these or the Dayton classic 8" 295-310 for sealed double woofer duty? Thanks.
The GRS would be better suited for a sealed enclosure. You can expect in room response into the upper 30's/lower 40's relatively easily.

Is the sealed Optimum Cabinet Size empty or with fill material?
The sealed cabinet sizes are modeled using typical fill which is roughly a half pound of stuffing per cubic foot of volume.
