All you have to do is avoid fixed images, especially the high contrast ones, and black bars for the first one or two hundred hours. After that, try to mix what you watch so that the same fixed images or black bars aren't in the same spots for long periods of time. I stopped being careful after 500 hours. I watch a lot of sports with fixed images, and movies with black bars. We also watch a lot of movies, and TV (on DVD) that is full screen without logos.
For instance, if you watch nothing but SD TV, with black side bars, for the first 100 hours and then switched to a full screen image, the sides of your screen would be brighter because they would be 100 hours younger due to the black bars.
If you mix material with side black bars, top and bottom black bars, black bars all around, and full screen images then your display would come close to aging at the same rate all over. In that example, you would need to watch a lot more full screen material to average out all those black bars.
Fixed images from gaming, channel logos, and tickers need more caution.
How much care you take depends a lot on your budget, and how often you can afford to replace a display that no longer pleases you. It takes a lot of abuse to make a plasma unwatchable, but some people go nuts at the first sign of image retention, let alone burn-in If the History Channel's high contrast and very bright logo started showing up in my movies, I would go ballistic.
should I run it all day and night
To do that you need a reliable source of images that fill the screen and have no fixed images. The only reason for doing that is if you're in a hurry. One reason to be in a hurry is if you don't have control over what others will be doing with your display while it's new. Let me know if that's the case and I'll suggest something that you can use.
... are there certain settings I should adjust to get the best picture?
You set has different modes. Just try them all and see what you like best. At the other end of "best" would be hiring a good professional to calibrate your display.
For owner reports about having their displays calibrated use the link at the bottom of my post. The flat panel reports are listed in post number two.
