Twenty Twelve Theme Edits. Widget and Checkout Button

Hope you are well.

I am creating a child theme with my edits so all sites will be the same and I won't lose any future changes.

However, two things. I need css coding for the widget bar? Can this be placed on the footer or on the left the page. It is defaulted to the right.

I do need code for the "price from" and the money symbol. Looks distasteful. Just price would be best. The store style is on "icons".

Any help would be great! The link is

I will place all code in the twentytwelve - child theme.

Appreciate in advance.
