Don't know, I never dabbled in the dark arts of AGA.

No, there is no "alpha" value in those early graphics chips.
If you write an OCS colour value, the first nibble doesn't count. I don't know if it must be set to zero though, or what happens if you don't, since I never tried that out. I guess it just doesn't get read.
so #$0fff is white, and #$0000 is black, #$0f00 is red, etc...
if you want to set your screen to a black background, you'd put..
dc.w $0180,$0000
in your copperlist. The $0180 here is short form for $dff180, which is the register responsible for colour 0, the background colour.. The copper understands writing this short form.
And what Roondar said. Get aquainted with OCS first.
AGA is really a lot more confusing, imo...
