Looking for a little help in customizing my site.

[Vestax159]

I'm looking to do a horizontal category drop down and a more traditional search bar. Similar to the ones found at www.shoplet.com is there any add ons I could do this with?

 

If you notice alot of sites have an image to the left and right of the main page sort of like a buffer from the site of the page. You can see this at the shoplet site I was wondering how to implement that into an STS template?
