I didn't read the entire thread, so I may have duplicated things...
Crate training is a must. Make sure you start with a small enough crate so they don't "live" on one end, and poop/pee on the other end. Is you start with a crate large enough for the adult version, use boxes or a gate to make it smaller when they are young.
Standard type commands - sit, down, place, here, no, heel
Leash training so they don't pull on the leash when they are older
Manners - No jumping on people (especially kids and elderly). This will take training your kids to not allow the dog to jump on them when they come home
House training - lots of good suggestions above. We have always trained ours to sit by the back door to go outside
Running Out the door - train them to wait on you go out a door, particularly the front door. They must recall easily before letting them off leash when not fenced in.
Fireworks - I like to get my dogs comfortable with gun fire, so when fireworks go off at NYE and July 4th, they done freak out
Bodies of Water - If you plan to have the dog around pools or lakes, introduce them to the water and what they are allowed to do in the water at an early age.
I'm sure there are more things. Good luck with the new pup
