Modifications to a cherry framework theme

General information for the website: Canvas Website
Kind of development: Customization of existing website
Description of requirements/features: My website that i am building is experimental.red-art.co.uk

Currently there are a few minor modifications that need to be made so that it is looking how i want.

Firstly, i need the tagline to be changed on the header. This would normally be simple in wordpress as you can customize such information at the themes > customise. However the cherry framework does not seem to be working properly, not allowing me to access this section.

Currently on the homepage, 'under new products' there are 4 columns displaying products. If this could be 3 columns with a max of 9 items stretched across the whole width on the page.

Also on all category pages like
http://experimental.red-art.co.uk/shop/ or
http://experimental.red-art.co.uk/product-category/canvas-pop-art/
i need it to not display a sidebar. But just 3 columns of products stretched across the width of the page with bigger thumbnails like the modification for the homepage.

I do need the sidebar to be displayed however on the actual product pages.. like
http://experimental.red-art.co.uk/product/r1062-canvas-wall-art-canvas-print-pop-art-joker/

It just needs to be removed from all category pages.


One last thing, when you add a canvas image to the basket, the image in the basket and checkout is broken. I cant work out why this is happening but it needs to be fixed.

Experience with wordpress and how the cherry framework works would be great
