i would just do the transmission fluid 2 more times. giving them one day intervals. if that stuff came out like mud...damn.

as far as the power steering and brake fluid...you should check the clarity. if it looks clear-ish, you're good. if it looks like tar, get it out of there. however, i never really heard of people draining their power-steering, except at goodyear when they want to charge 180 dollars to use a vacuum hose to clean it. that's exactly how i was told it was done.
