Make Magento RTL + Products viewable by members only

We would like to hire a developer to do 3 simple tasks with our Magento Store: 1/ Modify the Arabic View's CSS to make the store Right to Left (JUST FOR THE ARABIC VIEW) 2/ Make products viewable by members only: a/ Website is accessible to non-members - but when non-members click on a product to view the product page -> a java pop up will appear and ask the user to register or login. b/ The Java popup will look like the image attached. c/the Java popup in English View should be in english - the one in arabic view should be in Arabic - the one in French View should be in French 3/ Make the Countries list in the checkout in the arabic view in arabic language instead of english. (the countries in the arabic view are written in English)
