If I may make a suggestion. As CTM suggested, move the buttons to a 4x2. Remove "UGN Security BBS". Align the buttons top right. Add a background image of the height of your left banner and span the image to repeat (so that it spreads from left to right). 800 is likely to be the smallest user's resolution so make sure that both the left banner + 4 buttons in one row do not exceed 800...Preferably 780px.
