Quickbook using ShipRush

I have couple of questions with using ShipRush for Quickbooks shipping FedEx.

1)Can ShipRush writeback the tracking number into memo field in Quickbook?

2)What fields can be written back to csv file for the end of day shipping?

3)Can company logo be added to the shipping label?

4)Can you have both shipping for FedEx module and Stamps.com on the same computer using ShipRush?
