Miscellaneous Modifications to Existing Oscommerce Store

I have an existing, heavily modified oscommerce shop and am looking for the following: 1) Fix a small problem with Google Checkout. When an order is updated, I get the following error message: 1146 - Table 'retropolitan.google_orders' doesn't exist select google_order_number from google_orders where orders_id= 119 [TEP STOP] This should just amount to adding tables to the sql database. 2) Would like to add social media links to the site at large (in footer) and individual products (Facebook, Twitter, Google+, Buzz, etc.) in an organized manner. 3) Clean up some formatting problems due to a Center Shop add-on not working well. On some browsers/monitor settings, there is white space to the right of the top logo. Also, again sometimes, the right column drops below the individual product information page instead of remaining on the right. 4) Add a blog to the site (wordpress). Please contact with questions and thank you in advance.
