I'm replacing a driver for a Polk Audio model RM40T. This'll be my first endeavour. By all means, it seems it will be a perfect fit, but I don't know if it will have a noticeable difference in quality of sound between a poly cone and a paper cone, etc
Poly and paper cones share a lot of similarities in terms of tone, damping characteristics, etc. The difference in drivers will have more of an impact on sound than just the cone material alone.

recommends vented cabinet of 0.1cuft, will the inside dimensions 8"(H), 6(W),4(D), nearly correct?, also how about the vent? size, length of tube if not simple opening?
Yes those dimensions are going to work out just fine. I would recommend a 1" diameter, 2" long port for this application.

Will this work as a true full range speaker driver? I'm new to this and I would like to put this into a small bookshelf cabinet, run wire to it, and add binding posts, then call it good. Will this produce the full frequency spectrum?
This is a pretty subjective question. This driver plays pretty well up to about 10kHz but will start to lose volume above that. This would work well for some people as a full range, but others might want a bit more extension. Unfortunately I cannot say whether it would sound good enough for your application or not.
