The dock has a USB-C connection that supports DisplayPort 1.4. For G-Sync to work, at least DisplayPort 1.2 is required. Therefore, you can assume that G-Sync will also work via the dock.
I just bought a longer Thubderbolt cable separately for my dock, works great.
The power supply unit has a 3-pin Euro plug as the connection for the power cable. You can also find this if you search for "Mickey Mouse plug".
