Just to clarify:
There is no "must-do" order. Mix it up and see if it helps. This suggestion from JDsDream is good: connect at the windshield first, then you can push down on the top of the back corners enough to get them connected.
The engineer that helps me with installs almost always does it this way, by pushing down on the back corner, he "compresses" that bow enough to create some slack and then connects the rear corners.
