Website menu and body

website menu and body

I need to make a few modifications to my website. I need to change the menu color to a red gradient color. I have a little bit of space at the end of my menu so I need to resize my menu items so that they fill the whole menu. My slideshow stopped working, it only shows 1 item instead of 5 moving items. However, I still have a backup copy of my website that has the working slideshow in it so I think it should be easy to take the code from my backup and insert it into my current website. My ecommerce website is based on bigcommerce (website link is ProSoundGear.com). I will provide credentials and any other information you may need.

Also, on the front page, the products description is a little to the left and I would like to center it. I have the same problem with the footer image, it's a little to the left and needs to be centered as well. Also when you click on any product, the description overlays on the images.
