For 1 above - if you have a more complex animation that doesn't run through quickly enough within Poser, change to smooth shaded display then render with the current display settings instead of the render settings. It'll render out with all of the props and cloths in place but at lighting speed - it will take as long to render as it takes to play through within Poser. You'll get a good preview of your animation, and at exactly the same speed as the final rendered version would be.
