SEO, Edits to my prestashop

Hello,
I am looking for someone to help me with some issues I am having with my prestashop shop.
These are the areas I need help with
1) "Like" button below the products. Currently the button takes you to facebook or twitter. I just want it to like the product and post on there page.
2) forms sent to customers are pink I need them changed to the colours of the web site and prestashop taken out.
3) Need some renaming of links to match content of the page. Some links are broken and take you nowhere
4) I need SEO help. I want to get ranked well as a woman's clothing and lingerie boutique specializing in American brands. The store is in Edinburgh.

Please let me know your availability. I looking to take this live soon. I am almost there but struggling with some bits.
