AS3 template modification

I purchased a website template, [login to view URL], and I need custom modifications. As I can see I have only one image gallery with two level menu and I need is to add two more main image gallery categories and for each gallery category few sub image galleries This website sould be a gallery for kitchen company and each photo gallery is a designer and when you press a designer gallery you will have thumbs of the models. and when to press a model thums you should see few large images for the same model. Modification to the a gallery: when you press each thumb you will have the option see more images related the same model so the arrows should not go to the next model .... the arrows should let you go to next and back of the images related to the selected model the info should be allways open by default also for each image gallery I want to add a banner on top like in the home page and under this banner there will be the models thumbs This website should be with two languages, english and Hebrew, so I want to create the same website RTL (right to left) so the menu will be align to right and the text align to right
