Nice sandboxing! 
I have to admit that I haven't had time to do further testing or check your openings yet (I'll do that!). But do I read you correctly that you are also still leaning towards mining + worker first start? I should have time for planning later today & tomorrow, but it seems that we are not in a huge hurry and have a consensus for the first couple of turns?
I would not worry about warrior rushes from our opponents. In order to succeed we need to take some risks and if we are unlucky we can always 1-whip two warriors (2nd with overflow). (I don't know how far apart we are)
We are getting BW early enough for that. Our first need of military should relate to the safe transport of our settler to settle our 2nd city. At that point barbs are very likely not yet entering our borders (as the link explains).
