You can add more facilities than a planet can hold by using fill from list on the construction queue menu (I haven't tested to see if the extra facilities will actually be built yet).

On a related note... If you attempt to add more facilities than the planet will hold by simply clicking on a facility to add it to the queue the message stating that there is no more room will appear. You must hit Close twice for this window to close instead of just once. If you hit escape while this window is open it will close the construction queue window instead of the warning message.

Edit: I forgot to add that if you chose to have warp points located anywhere in the system that sometimes they will be located too close to a star (where half the hex is covered by the star and the other half is exposed) and you can't warp through them. You can, however, come through them from the other side. In effect they are one way warp points.
