I've built a bunch of bumpers for various rigs, and I can tell you that 3/8" is plenty strong for the load bearing portion of the bumper, and depending on the design may even be over kill. Only use the 3/8 for the center section, unless you're just looking to make the thing obscenely heavy. There is no need for any 1/2" in the build; I generally brace with 1/4" and it works out fine. I do make shackle tabs out of 1", but that really has nothing to do with mount strength for the winch. Good luck with your build.
Also, regarding the M12000, I see a LOT of these winches mounted incorrectly. When designing your mount remember that all of the Warn Heavy Weight series of winches are required to be mounted feet forward instead of feet down. All of the lighter winches can be mounted feet down, but that can and will damage a 12k winch. Reason being, the end plates are made out of aluminum, and when mounted feet down it will stretch the mounting bolts and rack the winch, bending the tie rods. I know this because I just bought a Warn M15000 for my trail truck that this had happened to. When the winch is mounted feet forward the winch mount bears the weight of the pull, not the mounting bolts and end plates.
