#1 will work. What you will need to do is when you select your
Yamaha input on the Adcom, set the volume to knob a easy to remember point, such as 12 o'clock. Then you can balance your channels for Dolby, etc. Now whenever you want to watch a movie, simply set the volume to 12 O'clock and your channel balance should be fine. This way, when watching movies you will use the Yamaha for volume control.
#2 connect your CD directly to the adcom, no need for 2 preamps in the chain, it can only degrade the sound.
Only caution: Make sure and turn the volume on the adcom down before listening to the CD, or you will get a loud surprise!
