447313 cross-browser compatibility issues (specifically IE)

Seeking to iron out the alignment problems that occur in IE8. Some versions of EI8 are apparently fine (IE 8.0.6001.18702), others are not (IE8.0.6001.17037 and IE8.0.6001.18943). I have not had the opportunity to test in all versions of IE8, nor in IE 6, 7, or 9, but would ultimately like the site to be fully cross-browser compatible. It was developed in firefox; seems to be fine in safari and opera except for some minor mis-alignment in the main content. Specific issues in IE: 1 - flush-top navigation is 1/2 hidden 2 - footer is not flush-bottom 3 - credits at very bottom are not horizontally aligned in the black area. 4 - some minor alignement problems in main content text.
