The EM and strong forces have no Higgs couplings, as their carrier particles (photons and gluons) are massless. There's no proposal of any Higgs with a color charge as far as I'm aware, and definitely not in a SUSY model.

One Higgs doublet is actually four particles, three of which get "eaten" by the W+, W-, and Z bosons to generate their masses. (In technical terms, they're Goldstone bosons which provide the longitudinal polarization component; compare with the photon, which is massless and has no longitudinal polarization.) The fourth is what we generally think of as the actual "Higgs boson." If there were two doublets, that pattern would be repeated, so in addition to h, we'd have H+, H-, H, and A. (The A is a bit confusing given that A is usually used for photons in electroweak unification, but that's the convention.)

I'm at Fermilab this summer (working on CMS, though) and there is definitely a sense of rivalry. The Tevatron can no longer claim the highest energy, but this has just shifted everyone's bragging to focus on luminosity, where it still dominates.
