One thing not mentioned by the others is a flight simulator (Condor). You could practice all sorts of emergencies with it at a very low cost. After that I would recommend more flight time and training. If you are in a club try a spot landing contest.

The rest of the gadgetry has a diminishing return on real safety and is highly dependent on what and where and how you are flying. For instance, I won't fly at Minden w/o a transponder, but Kansas might be a different story.
