I think the form feature where you can set qty's apply a unit cost into something like an order would be very usefull to our needs,
But we don't need the pay-pal hook, as these would be for our field operations to place orders to our own internal warehouse.
No payments will transact, but the form features would be very helpful.
Can these "store front' features be used without an actual payment transaction and setup?
The form you create for payments is no different than any other form (that doesn't have payments). There shouldn't be any reason why you could do you what you state above. Keep in mind that Payal does provide the "checkout" experience and not us. So you would lose that.
