I would get a good quality power bar, but other than that you should be more aware of the basic rules of plasma maintenance. Not sure how familiar you are with plasma TV sets but there are things that you should be careful of in the first 100-200 hours of use.
Image retention, burn-in, and uneven phosphor break-in are still the achilles' heel of plasma TV technology. While most new plasmas are very resistant to this, none are completely immune to it. This is especially true during the "break-in" period. It is consistently recommended that you only view full screen (no sidebars) HD content without having any static logos shown for long periods of time. Some individuals go as far as to break in their sets by running a DVD displaying blank screens of various colors for the first 150 hours of their TV's life. Essentially, you want to break in your panel evenly so you don't get a reduction in picture quality as the set ages.

Just to be clear, you don't need to run the break-in DVD, you just need to have full screen, non-static content on the display to break it in evenly. Viewing full screen Blu-Ray movies for the first 100-200 hours works just as well as the break-in disk while allowing you to enjoy your TV right away.
