As others said 73/76 should be good enough except for Classical and even then there are workarounds. I would think a lot about the touch and go for a weighted action for more expressiveness. Just my opinion.
As for shipping I had a Roland FP90 shipped to my house, heavy but no problem the way they pack them.
