Well, besides just poking around different threads on this site (and posting any questions you might have), I can recommend this book:
Opening Up: creating and sustaining open relationships ... by Tristan Taormino
Reading that book might give you a better understanding of things, and somewhat more of an idea of how you want to go about pursuing this poly life. It's a good book.
Remember that your poly experience is uniquely you. You can do lots of reading and studying (and you should), as well as conversing with polyamorists (e.g. through Polyamory.com here), but at some point you'll need to decide how *you*
would like to pursue this lovestyle.
No need to rush; give yourself some time to ease into this thing. And if you have any questions, let me know.
