Project: CRE Loaded 6.1a store mods

My store is a CREloaded 6.1a modified store selling almost entirely downloadable lecture videos. I need help with the following mods: 1. An easy way to access purchased downloads. (I am working on a "my downloads" page based on the download infobox, but it only shows the most recent purchase.) It is too cumbersome to go through prior invoices in the account history to find download links. I think I just need help constructing some kind of "SELECT" from the database with a 'while' loop to be able to echo all the valid downloads. 2. I need to bundle downloadable products. Example: someone wants to purchase a lecture "series" on a topic, and I want to be able to price that bundle differently from individual products and also that each component of the bundled series would show up in their download links. I have looked at "bundled products" contrib for OSC, but couldn't get it to work.
