QVSource was acquired by Qlik about a year ago and is now called the Qlik Web Connectors. This has the Qlik SugarCRM connector that you're referring to.
You can get the Qlik Web Connectors from the Qlik download site, where you find the usual downloads, and is under the 'connectors' tab.
As it's a Premium Connector, you will need to request a trial LEF to have a play with this, but from the download there are a number of Standard Connectors, as well as some beta connectors, which are free to use. Although you may not need these other connectors, since they all work in a consistent manner by playing around for them you can get a feel for how the product generally works.
As for the Qlik SugarCRM Connector, here are some of the tables that you can access:
