Nice project. Lots of good info above. Keep the root damp till you can get um in the ground. Id throw them in a 5 gal bucket with enough water to cover roots when heading out to plant. +1 to planting depth mentioned by Pat, Too high or too low will slow growth down in a big way, also can impact long term health of the tree. That's the biggest mistake I see people do.
Only thing I can think to add is it looks like some are branching?? I'd prune any side shoots off at planting. Good luck with this project.
