Custompress Marketpress or Both ?

I need a product catalog system for display and inquiry purposes only.
Here are the things i need
1) Product management (add edit delete) and display with prices
2) Multiple images with each product
3) Inquiry form on product detail page
4) Category/Sub category navigation
5) Search products based on keywords or attributes
Since i wont have a shopping cart, do i need marketpress at all ?
I would have only one product type and the product will have a lot of attributes like Price, Color, Location etc
Should i use taxonomies for these attributes ?
