Welcome aboard tbestes, have you played with setting the z-index on #navcontainer only?
You have #navcontainer at 100 with a table nested inside it, and are attempting to get the menus themselves at a higher z-index - the problem is, the position is relative, not absolute, so it doesn't pull them out of the natural flow (e.g., it may not be working.)
First thing I'd do is lose the table used for layout (it's not needed,) and probably set position:relative on whatever container is holding #navcontainer. Setting relative on the parent will allow you to use position:absolute on #navcontainer, and it will now be positioned absolutely relative to it's parent (sounds contradictory, but it's not.) You can then set z-index to 1000 on #navcontainer which will bring the entire container up in the z-index.
