Welcome to the forum!
There is a ton of stuff to read here - most of it unfiltered - you can search for tags when you know what sort of thing you are looking for. Hard to know where to start, though, so may I recommend this excellent set of articles: http://www.xeromag.com/fvpoly.html
That one page, without following any of the links, gives you a ton of stuff.
Working out whether poly is for you, and which type of poly suits you (because there are many types) is a journey unto itself. If you have specific questions, please feel free to start a thread on them.
