I recently picked up a Choate tactical stock for a long action. I mounted it up to a 110FP. It was $198.97 on the nose with free shipping.
I like it a lot so far and the functionality has been great but on that 110 FP it was a lot of black in one place, so I did a sponge camo job on it.

As far as choosing caliber I'm not a fan of the 7-08. It doesn't do anything better than a .308 at any practical range and costs a good bit more to run with less available components.
It recoils just as hard on the shoulder, it's just as loud, the naked eye can barely tell em apart, and their aint a hill of beans worth of difference except in the wallet.
