ECJC Cart Expert Needed -Paypal Questions

I need someone to assist with the following 4 issues: 1. Need helping configuring with Paypal 2. Need to know how to build this functionality into our ECJC cart. We have clients purchase the product, and then in the cart we want to be able to add in support packages - 1 month, 3 mo, 6 mo, 1 year... how do we code these as additional purchases in the cart before checkout. They would be recurring monthly payments 2. I see the backend of the points tracking system but cna't seem to figure out how to show clients there point balances in the cart. Suggestions? 4. have website payments pro and when it uses debit/credit card it brings buyers back to right page, but if someone was to pay via express pay it doens't process transcation or bring buyers back to the right page of the website. Paypal technicians tells me this is in ECJC cart and i've fixed auto return link on the profile page in paypal account but nothing working. If you don't know these ECJC and Joomla don't respond.
