GRS 8PR-8 8" Poly Cone Rubber Surround Woofer
How would these work in an Acoustic Research AR-18b? (.34 cubic feet, sealed, 2000 hz crossover 88db sensitivity.) Would the paper GRS 8PF-8 be better? Or some other 8" woofer?
Either option will work well in that speaker. The rubber surround on this model will last much longer than the foam of the other however.

How does this unit preform when ported?
With the very high Qts this will have a large bump around F3 which can be undesirable. It will act as a natural bass boost, so if you like the bass turned up or loudness button pressed you may like how it sounds.

Would this woofer be a good replacement for a pioneer model CS 44 ?
This might be a good option. The main thing to check would be the actual driver dimensions. There is some variation on speaker frames so the outside diameter and cutout is important

Port size for 12x16x12 box tuned for 50hz
I will be making some 2-way home theator speakers, I would like to tune the 12x16x12 boxes for around 50Hz. Also, Would a pvc pipe work for a port? I have used them in the past with DIY speakers, and have had no trouble, thanks!
A 2" diameter, 2" long port is required to tune those enclosures to 50 Hz. Yes PVC pipe will work perfectly as port tubes.

Will these work well as replacements for dual 8's in a 1.5 cu.ft box?
I have a vintage Jennings Research cabinet that uses 2-8"ers in a sealed box. Crossed over at 2500hz and 500hz respectively.I see from the specs that PE recommends smaller box and since there's 2 drivers can essentially double the box size? Which would be about 1.6 cuft. But, Qts looks like they should want bigger box?
These will work fine for that application. The box size we have listed is a high Q alignment because the optimally flat volume is quite large.
