Peter,
I have both the D600 and D750 and yes they are very similar but with some differences. I don't think you will have any issues switching between the two, but I also would recommend downloaded both manuals and going through them to pinpoint the differences that might affect you. Then just make a list of the settings you want on the D750 before you go and shouldn't take more than a few minutes to setup the D750.
And yes the items you mentioned are correct.
Good Luck,
Roy
