Help with custom post type 'Marketplace Items' setup

I would like to set up a custom post type called 'Marketplace Items' (let me know if keeping this to one word such as Marketplace would be preferable). I have a good start but am not quite there. I need them to have a hierarchical category structure just like pages and need to add a few meta boxes (in the main portion of the admin not the right side) and have them store data. I would love to get a query for the front-end as well! I have a pastebin of my start here:

The meta boxes that I need (just simple text fields) are:

member name
retailer name
manufacturer name
SKU
product name (dont need a meta box for this one- can just be the title field)
retail price
sale price
description (dont need a meta box for this one- can just be the main edit textfield)
image URL
