Virtuemart Shipping Module/Joomla tidyup

Only bid if you are expereinced with Joomla/ Virtuemart shipping I am developing a virtuemart site to sell books for a non profit mission to the poor using Virtuemart 1.1.3 on Joomla 1.5.4 1. Shop a. Add to cart shows up for some books and not for others on the urbanbooks page - no apparent reason. b. Don't want any featured products, not sure where to turn this off c. Cannot add a second book of the same or change the total. It does not show anything was added. I saw somewhere on teh forum that someone had fixed this but can't track it down d. There was navigation between the book flypages but this seems to have disappeared. 2. Checkout a. Billing and address information is clunky. Formatting needs tidying b. Dont want fax numbers 3. Errors in the shipping module Using standard shipping. Maybe there is a better module to use. Everything is set up in NZ$. Paypal would not let me pay in NZ $ to ship something to the US, I think Be easier to have these set up in a table format by number of books x country or world region and they can click the appropriate box rather than so many options. 4. Need to update Joomla to latest 1.5.12 from 1.5.4 on my home stie [login to view URL] and 1.5.11 to 12 on the subsite [login to view URL]
