WP e-commerce | blogshop

Hello !
I need some help:
First – look at my blog, You can see the shopping cart up in the left corner. Please click “visit the shop”
Here are the links blue. Where can i change this link colors?

Second – then click under the polymer clay group, choose one of the categories below or both. If you look in Explorer netbrowser you will see that the products are fine, but it you see in Firefox the products have a huge empty space from header to the products…..! Why do the empty space come from? Can you see it ?

Third – Look under menu. Shouldn`t it be some text/information under YOUR ACCOUNT and Transaction Results? What should be here ? Is it for my costumers ?

I need this help so i can get my shop going…. Thank you !
