Thank you Loner T! No.4 resolved the issue. Boot Camp and the drivers didn't install fully with Windows installation.
I downloaded the Windows Support Drivers, then OSX got stuck with the message:

In Disk Utility I saw a ghosted out unmounted Boot Camp drive and mounted it. On my Mac Desktop the drive icon appeared. I copied the all the files from the Boot Camp Drive to the Windows drive partition, I copied them to the Windows Desktop in a folder I created "Bootcamp drivers" .
Reboot into Windows and run Setup.exe I found in the 'Bootcamp drivers' folder I.
It installed all the drivers.
Now the sound works fine as well as the Magic Mouse 2's scroll and the keyboards Mac functions...bonus!
Also, I didn't have the Boot Camp icon before. No wonder most functions didn't work.

Now everything is just groovy. Still need to get a great PC gaming mouse.
Just to answer your Question 2.
