A J/24, or any J/Boat for that matter, is a tough boat to beat. The pointing ability is supurb. I know as I have a J/32 (cruiser). I sailed a J/24 once (when I still owned my Freedom 21) and found that the windex (apparent wind indicator) was less than 5 degrees!

A common item is to use TOT (Time on Time) vs. TOD (Time on Distance). It evens things out a bit.http://www.ussailing.org/phrf/TOT.asp
The following article also gives of nice explanation of how it works with both TOD and TOT:http://aroundthebuoys.com/html/time_on_time.html
I also agree that you should get yourself the “Class” (overlapping) staysail and sail as a sloop vs. a cat. Take the PHRF “hit” for some better pointing ability. Having done some “Beer Can” racing under both, it is a lot better.
