CSS and AS help needed TODAY!

I have a project that is nearing deadline and I need a few tweaks on a CSS menu file and a piece of action script that will do a simple mouseover effect. The CSS menu is done and works fine with two exceptions: 1 - I need the selected menu item to remain 'open' or 'visible' after the user's menu option has been clicked. 2 - It is a vertical main menu that has a horizontal 'fly-out' sub menu. The SUB-MENU has another sub layer that is currently vertical, but I need it to be horizontal. The AS needs to increase a thumbnail by 20% when moused over. *THERE'S GOOD MONEY FOR THE CODER WHO CAN COMPLETE THIS TODAY!!! *
