In my experience it increases PSNR somewhat. Of course, PSNR isn't everything, but with such small differences it's nice to have a quantifiable comparison.
I also considered using mbd=1, or is that the default when using vhq? I mean if there's a difference between the "vhq" turned on by mbd=1 and the vhq parameter, what is it? And if not, do they work well together?

As far as I know, vhq is just an alias for mbd=1. You might as well try mbd=2, though. My tests have shown it to increase psnr somewhat, again.
I don't really understand mbd=2, but I'd recommend doing some testing. It might only improve psnr with 2pass encoding. Rich
