Yep. All your points sound correct.

In my Last PBW game, I concentrated on my 1 opponent that had not developed any intel, and later on switched to another opponent that had. The second opponent countered about every 2nd or 3rd project I threw at him, because I had quite a bit more intel points.

If you have a partnership treaty with someone, you trade Intel points just like resources and research. So depending on your treaty situation, you may get some advantage before you build any facilities yourself.
