You have the "nav_bar" floated left. You should wrap the "nav_main2" and "container_2" div's inside another div and have the new wrapper div floated left also. This will make is so you don't have to try and move those two right with positioning or margins.
But the strangest thing happened after that fix.. On the pages where I actually have some written content (specifically the Property Management page and the Gallery Pages) the whole tops links and content container FALL below my image button links..?? I've tried changing various attributes like limiting the text width, content box width, etc.. I can't figure it out?
