URL Changes, Auto meta Tags, Retail Price Fixing

There will be urls changes that needs to be done in the site such as: [login to view URL] (information page) [login to view URL] (Category page) category=Swiss-Replicas/VACHERON-CONSTANTIN (Sub-category Page) [login to view URL] (Product page) Now i want it to be something like this: /about (information page) [login to view URL] (category page) swiss-replica-watches/[login to view URL] (Sub-categories page) swiss-replica-watches/omega/[login to view URL] (Product page) You will have to set seo indexing urls correctly; then edit the .htaccess file and check the codings in root/lib/general/php it is the place where all the urls etc can be conducted. Along with it I want an auto tags to be written for products pages. Something like this just for the products. Product Page Title: "Product name" at "website name" Product Page Desc: "Get a top quality "product name" from "website name" for just "Price US$". It can be conducted in [login to view URL] file. Codings needs to change out there. For categories and information pages it's already there in the admin. Also last but not the least; i want retail price to be displayed like (save 20% on this product). It is there to input in the admin but i think it needs to be properly configured in the product; categories displaying product pages. It is bigcommerce interspire cms.
