Well, not to be too nitpicky as well, but I think it's pretty well accepted that QCD is the theory of the strong interactions (of course, it depends on what you mean by "high" energies). What asymptotic freedom means is that you can calculate QCD perturbatively at high enough energies, but, as you mentioned, at lower energies you can't. But just because we can't always get answers out of QCD doesn't mean that it's not right - just, as you said, we don't completely understand it.
But it's still a fascinating subject to work on. Oh, and to be fair, lattice QCD calculations nowadays are getting well below 10% precision for certain quantities, and improving all of the time - so it'll be interesting to see what happens there.
