Hi,
There are some other options to hide the "prices" from a specific shopper.
Such as; you might want to hide the prices from "not-logged in" users. Virtuemart is capable to do it.
Maybe you did this, i can't be sure. Do the prices get shown once you logged in to website?
If you it is obvious you did that, open any product and see the screenshot:

About making visible "ratings" but hiding all other TABS, see your email. I am emailing you modified PHP file. Override it with the one you have now, you will get what you want.
Regards.
