Hi Mitch,
Welcome to the MEPD! I had the very same questions when I got started. Most of us purchase armor "kits" from vetted makers and then assemble them ourselves. You can find a list of makers on the FISD forums here at http://www.whitearmor.net/forum/topic/11538-the-various-types-of-armor-and-where-to-find-them/.
The kits will vary with regards to material, price, and wait-time, but all should get you an armor you'll be proud of. For what it's worth, I elected to go with Authentic Props (AP) armor.
Good luck!
