SimpleMarket change colour, pics in grid view and remove blog posts

Hope you are well.
I have three concerns when moving from GridMarket to SimpleMarket.
I can't change the colour of the fonts and words from the horrible green.
The product pics also show in single line underneath each other. I used this code. Does it need to change. [mp_list_products paginate="true" page="1" per_page="10" order_by="title" order="DESC"]

It also shows on the products page. The blog post.
regards,
Lisa
