All of Gabrych's run is out in trade form. These two issues plus the Brotherhood of Evil arc (60-62) are all in a trade together called Kicking Assassins.
Before that there's Fresh Blood which was a crossover with Robin. Then the trade after this one is Destruction's Daughter which has #65-73.
Puckett and Scott's run is all but collected in various trade form but they're kinda hard to get. Alas to say the final arc and story of their run isn't in trade form yet. Neither is the middle run. You're going to have to go back issue hunting alas.
