Here are a few tips for paper space viewports.

Double-clicking in a paper space viewport will allow you to manipulate the model space view within the viewport.  Typically you are setting up a view by panning and zooming to the correct location after doing this.  A really easy way to help make this process easier is to be saving views to be used in the viewports when you are working on your objects in model space.  Now when you set up a viewport and enter model space mode of the viewport, simply type in QV to open the Quick View dialogue box and choose your saved view.  A little forethought as you work in model space goes a long way in your paper space viewports.
