No need to water down the idea too much by offering bad items in the shops
The shop should also contain anglers. You can already do every piece of end game PVM with just swordfish (I do it myself because I cba to fish) so theres no need to exclude anglers from this. Nobody would ever fish anglers, they would just settle for sharks because +2 isn't enough to matter in PVM.
Being Limitted to sharks also fucks the idea of Ironmen pking since they'd be at a disadvantage to any pkers who aren't ironmen.
Should be every pot (including combat/stamina/venom). You already get more herbs on Ironman than pots you use. It would be annoying still having to make pots just for the sake of it when we already have 5k of each herb noted.
The alternative and better idea for this would be to make a shop where Iron Men can just trade in their Grimy/Clean herbs & some coins for finished 4 dose potions. (after 99 herblore). Since the BM shop contains the herb box it would give Ironmen a way to supply themselves potions whilst pking.
