While on the numbers kick, I also figured that I would add that only 136,932 harvest report cards were recieved by the PGC for the 2006-2007 season (thats is both antlered and antlerless as well as for all seasons). Also, the PGC personnel examined a total of 29,581 deer in the field or at processing stations.

Now, the PGC also reports that there were a total of 64,820 deer harvested by archers. Now, subtract that 64,820 archery kills from the total of 361,560 and you get 296,740 total firearms kills. Now, assuming that there are 1,000,000 hunters in PA, that puts the "firearms hunters" success rate around 29-30%, which is only about 2% higher than what you have listed for VA's archery hunters success rate.
