Hi Paul and welcome!
Sounds like you're interested in becoming a Stormtrooper? The good news is, you won't have to mold or shape any plastic, there's a few vendors out there that you can find online that can get you a kit to put together! There's quite a few people that are waiting on kits to come in (lots of vendors have a wait time) and I'm sure you'll end up being one of many folks building a Stormtrooper over the next 6 months! I'd imagine there will be a number of "armor parties" happening where folks new and experienced can hang out and help each build their kits.

http://www.whitearmor.net/forum/ aka: The First Imperial Stormtroooper Detachment (FISD) it's an amazing resource for all things Stormtrooper and get ready to spend hours and hours reading about how to build your kit, follow other people building their kits, etc. Don't get too daunted by all the info, and always feel free to ask questions! Also, check out their "approved vendor" thread. Basically, do NOT buy your armor on eBay. It'll be really awful and a major bummer.
There's an officially licensed kit that's not out yet from Anovos @
www.anovos.com While buying it and putting it together doesn't mean you're guaranteed membership (you still need to have it fit right, have the right pieces in the places, etc.) it's not a bad place to get your armor. The initial batch of kits is supposed to be shipping late Nov/early Dec, but if you order now, I don't know when your kit would ship.
I joined early this year, so I remember the "I don't know where to start!" feeling early on, so don't feel like it's too crazy. It's totally worth all the time and effort, it's been awesome this year!
