If you primarily view HD material, would opt for a 50 - 55" panel at that distance. A 60" would look fine with blu-rays - marginal with less-than-HD programming (that is, almost Anything Else...).
For SD programming, including SD DVDs, would stick with a 50". If you view Mixed Programming, but expect a transition to more HD material, 55" makes a wonderful "compromise" size.
?? as to Windows depends upon their location in relationship to the panel, whether you have any covering (drapes / curtains / blinds....) for them, the direction they face, and how much viewing you do at the "difficult" times of day (for your location).
Note that few panels have a Matte Finish now (visit Cnet: they maintain a running list of matte finish sets), and thus Reflections can be a problem for most LCDs as well as Plasma panels.
Plasma still provides much better off-angle viewing than LCD sets - but the latter do vary, with some being distinctly better than others (Consumer Reports rates panels for Viewing Angle, and would be worth looking at).
Good luck with your research!
