Good idea on the flood lights. I'd also include "garden lighting" around the flower beds and under the windows to make sure there are no dark shadows to hide in anywhere near a possible entry point. Might want to consider lighting the entire length of the driveway, or at least both ends. I have closed circuit cameras here, one on the front door, one looking out the front window, and one in the back. (not as much need in back due to the layout and orientation of my place)
Reinforce the doorjambs with sheet steel or angle iron. I think they make a product to do this but it may or may not be cheaper to fabricate your own depending on your skill level and tools. Make sure you use a nice solid door and a good lockset with a deadbolt. Right now I've got really cruddy windows, but I'll be replacing those soon with something a little more sturdy and I may add cast iron grilles to the windows mounted to the bricks outside. Make sure you fence in your property and post no trespassing signs. Posting your property (no trespassing, guard dog) according to whatever regulation exists is important also, to help prevent any liability (if possible in your jurisdiction).
