I'll definitely pre-order the bits you linked - after reading others' threads I'd prefer the 30-minute job (including beer!) versus days of frustration and injury.
Get yourself a bottle of Castrol Moly-Dee CF Variocut C cutting and tapping fluid, apply a little to the bit before you start drilling every hole. Trust me it’s worth the cost of the bottle when you’re drilling and tapping holes on a pig. You can find it on eBay pretty cheap.
I think I can wrangle up an air hammer from Dan or Tasche, but will let you know.
You’ll need an air hammer that has a longer piston stroke like Ingersoll Rand 117, I bought mine from the Snap-On truck but it’s probably just a rebranded IR.
