Savage 10 build from receiver

A few months ago I bought a savage 10 (308) receiver w/ trigger and bolt to do a rifle build. Shortly thereafter I bought a boyds stock - FEATHERWEIGHT THUMBHOLE SAVAGE® 10 DETACHABLE BOX MAGAZINE SHORT ACTION FACTORY BARREL CHANNEL FOREST CAMO LAMINATE (FINISHED) (430064D-06-110)

In my lack of understanding, I didn't realize that I needed a metal surround, or anything of that nature. Now I'm wanting to complete this build and want to *try* and get the rifle complete. I realize that there are a few surrounds and a few options, even a AICS platform that would allow me to use higher capacity detachable magazines.

So, i'm trying (in futility) to find what all sort of parts I need to use something like the CDI precision trigger guard (http://www.midwayusa.com/product/769...-screw-spacing), but want to make darn sure it will work on the firearm before i order. Additionally I need to know if there are other parts to order to complete the build.
