Modifications to Prestashop Site

I need a few modifications made to a Prestashop website which contains a Wordpress blog. Screenshots are attached to clarify what I need done. 1) Modify Website Blog Page I have installed and set up the Inveobusiness Wordpress integration module for the site. [login to view URL] There is additional space at the top of the blog, which needs to be removed. Also, the Posts heading needs to be removed (see screenshot). The blog text should be left aligned on the site and take up more available space. Also, unlike the rest of the site, the Categories on the left column do not appear. This needs to be fixed as well. 2) The banner at the top needs to be positioned in the middle. 3) A search bar needs to be added at the top of the page 4) The active menu (top menu) has stopped working on all pages but the front page. This needs to be fixed. 5) On Category pages, Previous, Next is misaligned. It needs to be placed properly. 6) The Add to Cart button needs to be modified. I would like it to look like the button used by Amazon, but with a red, white and blue design. 7) The powder blue background on the site needs to be changed to the same color blue found on the American flag.
