XML-Driven Drop-Down Menu roll-over help

(First Time Poster) Can anybody help, I am using the XML-Driven Drop-Down Menu from the tutorial on this site and all is great but I have a couple of features I want to add to it but I’m not an actionscripter.

Firstly is it possible to have a roll-over state on a menu item stay on while while you are displaying it’s items. I have 10 menu items at the first level and 9 of then have sub-menus so I need it to be seen at a glance which submenu you are on?

Secondly how would I include a different icon to each of the first level menu items?
Could that be done via the xml, or would I need to include more AS to call items in the library?

Any help would be greatly appreciated.

cheers
