How do I decrease the font in the navigation?

I have 4 columns, including a top bar:

-------------------------
|________1________|_4_|
|_2______|___3____|_4_|
--------------------------

Column 4 is my YUI Site navigation module.
My navigation has a lot of links in it. Whenever a navigation option is expanded, this increases the space above and below column 1, so it pushes columns 2 & 3 to the bottom. When several options are expanded this messes up the whole page.

What can be done to resolve this?

Does anyone know how to add custom icons to the navigation module, like discussed here?
And how to add alt tags, like discussed here?

It would be useful to dynamically load data, as discussed here, because this will make the navigation load much quicker. Users will only need to see the parts of the tree that they select. The rest does not need to be loaded with every page load. this will also avoid the weird effect that this module has, that makes the whole module expand when the page loads.
