For question #1, I don't think it matters if you use one hole or the other. I would consider the function of the holes relative to fit and form requirments to determine which is better. Depending on the function of the holes relative to each other, or any particular side of the part. I would then tolerance appropriately relative to function. By selecting the datum's based on function, i.e. a surface or hole feature, you will ensure the design intent is met.Question #2, I would reference the holes simultaneously using position tolerance relative (establish datum's) to the controlled (manufactured) surface of the fold. I do know that manufacturing the hole features will likely be done simultaneously, that is, within the same setup. With this, the sheet metal part would the positioned for that operation against selected (datum) surfaces. Hope this helps!!
