Panther, there IS a box blade that Bobcat has out that works on the Toolcat. It is P/N 6906574. There is also a box scraper, P/N 6958483 that will work on your machine as well. As far as the laser use, I don't see the point for a driveway. It's over 10K for a transmitter, receiver and harnesses. Plus, the Toolcat is not wired like the skidloaders and it will not run the blade with a laser attached as the Toolcat has no BICS on it.
The box scraper works GREAT on the Toolcat. It has a cutter edge on the rear that swings away when going forward but cuts when backing up. Mount it on a Tilt-Tach and you can crown your drive very nicely.
