Fear not: it's are not as bad as you think!
Let me explain:
(1) The graphical bug (things floating around) is Vista-specific.
(2) The BSOD bug is related to nVidia cards (unless you have a different brand of card, in which case we have a new problem).
(3) Both of these bugs will be targeted in their own update very soon, once Karl finishes classes next week. (There should be an update today, another update next week, and then the update to kill these bugs in the next couple weeks after that, depending on how things go).
As for the sound bug, I have not experienced that (I run Vista). I do, however, lose sound when I'm running the game full-screen and alt-tab out: when I return to the game I don't have sound anymore. Is that what you're experiencing, or is it something else?
