WordPress Template Configuration / modifications

I have a WordPress template from Themeforest which I need minor modifications done to.

Here is the link to the original template: http://themeforest.net/item/ewa-bootstrap-multipurpose-wordpress-theme/full_screen_preview/4661526

And it is the first template in the third row.

The link to our website is: http://ladylibertilingerie.com/

The brief therefore is as follows:

Home Page:

1.Six promo boxes (instead of just three)
2.Position the six promo boxes as per template (to enable view wall-paper).
3.Narrow the space between the last row (of boxes) and upper boarder (of the grey info area)
4.Narrow the column space between the six promo boxes (similar to template).
5.Remove bar/strip (area) containing "My Account" and Shopping Cart.
6.Re-position shopping cart onto the top bar.
7.Re-position "Search" field onto the top bar

Category Page:

1. Insert Four Columns
2.Resolve image proportions to enable full view.
3.Resolve text overlay.
4. Insert required field to display Brand name

Product Page:
1. Insert required field for Brand name, to be positioned below product name.

That's pretty much for now. let me know whether this is doable.

Thanks and looking to hearing from you soon.

Regards

John
