Problems with IE6

My site template is functioning properly except in IE 6.

When you hover over the drop down mega menu in IE 6, the rotating featured content boxes jumps down...there is also too much space in between the nav and the content box. Any ideas on how to fix this?

Also, I've managed to get a blue border around the nav buttons in hover state in Firefox/Google Chrome...but if I try to add it for IE6, the whole menu gets buggered up...any ideas?

Thanks so much for your time!
