Personally I'd put shoulders with Triceps and Chest and Abs with Back and biceps.
But honestly I might agree with Scott, at this point you really shouldn't be trying to write your own programs and would probably be better off just following one of the programs found on this site.
EDT isn't my favorite program personally (though I have done programs based on progression by density), but yeah, it might be best for you to just follow a program for a few months, get your nutrition down and stop obsessing over building your traps, forearms, and triceps.
When you stop making progress on EDT try something else. Really any balanced program that allows you to continually make progress (weight on the bar or more reps with the same weight) combined with a good diet and sufficient rest is going to give you results.
Constantly overanalyzing and obsessing about working a couple of muscles isn't doing you any good however. Just do as Scott said, pick an already written out program (that is written by a professional), follow it, get your diet in order and learn as much as you can from it. Since he mentioned EDT, and since EDT is a fairly simple program that basically forces you to continually progress, why don't you just go with that.
When you plateau, come back here, post your results, post your diet and then if you want perhaps we can write you out a program. You'll have proven your willingness to take advice, and that you are serious about making progress.
I know that this may not be what you want to hear, and I am tempted to write you out a program, but Scott's right, giving you yet another option to choose from isn't really helping. There are already so many conflicting pieces of advice out there, and programs with what seem like complete opposite protocols that posting a program for you is just going to compound the problem.
