Code Clean Up: Jquery/CSS/PHP

I have some very messy code I need cleaned up. There's a lot of extra DIV tags I would like to clean up and get rid of. I want this as clean as possible. Also there's a flicker of hidden divs also before the jquery hides them. I'd like to avoid that. I'd also like to rename relevant DIVs to longer, more descriptive names. ## Deliverables Code to be cleaned up is attached. I also have new graphics I would like to use for the new web page. The new page is all new and if you'd like to change the current look to the new look as well, let me know.
