I've added a copy of the site I'm working on to my server, and created usernames and passwords for WP and ftp logins. (if ftp gives you trouble try port 21)
Just to outline the file structure
Product Post Type (post type and custom taxonomy are registered here)
I've added the asp filtering code to the top of the functions file to make it easier to find
I think I've moved all the custom styles to the plugin interface, but in case something is missing, most of the theme's styles are contained in library/css/main.cc
Lastly, I'm also have trouble setting a gutter width for the isotopic search results. For the normal grid display I'm using the standard jquery isotope plugin – would that somehow cause a conflict?
many thanks again for all your help,
