Custom Post Type design, plugin advice

Ok so i’ve been given a design for a product page to go on a site i’m building. I need some advice on what plugins to use and what’s actually possible.

1) There’s a menu on the left side which shows different products and categories on a about three levels.

I’m thinking i could put a sidebar widget area on the left and have an accordion menu widget.

2) The main content of the page is the product details. There’s a product description with an image and also various tabs. Things like features and downloads for the product.

I’ve seen various plugins that can do the tab thing but they all involve shortcodes. Ideally it needs to be different editors for each tab (when i say editors i mean the wysiswg editor when created a page).

For example the first editor will be the description, then another editor will be content for the features tab. Another section to attach downloads for the downloads tab.

3) There is a section below the product which is a call back section.

I’m thinking for this another widget section and a contact form widget. It shows the phone number, a request demo and request quote. It also has a small form for name when to call back and telephone number.

4) Finally there is a related products section at the bottom. Which is a slider with images and titles of the product.

For this i’m not sure about. I’ve looked at various related post plugins but i’ve not seen one that would be a small slider with images of related products.

I know i’ve asked a lot here but any help, plugin suggestions or anything will be greatly appreciated.

Thanks
