comment How to avoid labeling features if overlapped by another layer?
While I wasn't working with a DB layer directly, this solution made the most sense to me, as it did not require editing the geometry of the initial data sources (other than loading them into the DB). This is a great example of thinking outside the box of shapefiles and application limitations, and finding a creative solution to the problem by combining both application and DB logic.

Thanks, the plugin sounds promising, so I will give it a try.

You make a valid point that I could create a new dataset (which would be easy to do in this case... just erase out the line features under polygons), doubling up datasets doesn't sound too appealing or manageable, unless you use a database-driven method like @Richard Law mentioned.

These were shapefiles, but your idea of moving to PostGIS and managing the data issues on the fly is a really good one. I would suggest you move your comment to an Answer, since I could make a pretty valid argument that this is a good resolution.
