Showcase Theme and doing some basic edits

OK so I am liking this Showcase theme alot. I want to build a client's online quilt shop using it. I attached a screen shot of an individual product page. In the top right it shows Admin and Date. These I do not need and would like to remove them. Are there simple edits for things like this that I am missing or should I be doing this in the Editor? Secondly, and this is probably a separate topic but I want to replace that area with a simple horizontal style cart. Maybe just display how many items are in the cart with a link leading to the full cart page. Anyway, any of this possible? I see shortcodes and widgets but no php codes for adding a cart etc. Thanks.
