Ed,
I don't think you are going overboard but it may not need all of your considerations for packing. My first Bandsaw was one I bought on ebay. Because it was damaged during shipment and thankfully it was insured, I got my money back and even got to keep the damaged Bandsaw. So here is what happened to it. It was packaged as shown below still completely assembled. That included the Mounting Posts still in place.

Not a very good packing job.
At some point it was dropped during shipment driving one Mounting Post up into the stop. This caused the damage to the Main Frame as shown below.

I replaced the Main Frame and now have a nice Bandsaw which has been my primary one since it's repair. The other two Bandsaws I have purchased that were shipped to me arrived well packaged with no damage.
Removing the Table and Mounting Posts is, as you can see, a good idea. I have a Bandsaw shipping box (with a Bandsaw stored in it) that Shopsmith uses. It is shipped from the factory in one box with the Table (cast Iron or Aluminum now) and the Mounting Posts removed. The Trunnions are left in place and the 4 bolts removed to remove the Table. Because of the drive Shaft extending out the back of the Main Frame packing in the form of expanding foam and a plastic cover encasing the foam is used. The Bandsaw sits into that packing which can include space for the table to be behind the Bandsaw itself with padding between the Table and Bandsaw. The Mounting Posts can sit between the upper and lower guides in the space there. Finish off with some packing to protect the front to the top of the box and you're ready to ship. Use a box large enough top to bottom for the back including the drive shaft to the front.
