Hi Smokey!
Welcome to WnW addiction.
For start, if you want to use wood decals, I would tell you to go uschi ones, that you can get at, http://www.uschivdr.com/
For turnbuckles, the best you can get are Gaspatch Models ones (http://www.gaspatchmodels.com/products/metal-turnbuckles-32.html) but they are expensive. You can see several pcis on wnw website and Albatross instructions that for sure will help you choose the turnbuckle type. I personally go for the Bob Buckles.
As for rigging, you got EZline (that you can get directly for Wnw) and fishing wire.
