I think almost every spell should be reexamined, not just the ones with HD limits. Not only have monster HPs been boosted, but their saves as well. So spells with no HD limit are still impacted by the mobs boosted saves, stats, etc..
IMO, this is a symptom of the larger problem of power creep/inflation/mistakes or whatever you want to call it. There is something of a balance in PnP between weapons/spells/monsters. It isn't perfect, but what is. When you introduce crafting, greensteel, Khopesh implementation, and other inflation into the game, you then have to boost the mobs HPs, saves, etc., which in turn breaks spells based on HDs, etc. so you have to boost them. When one area gets boosted or nerfed, it affects everything else. It's all a balancing act, and ideally gets done simultaneously.
