It should be straightforward to wrap an NSBitmapImageRep around some

is. While GWorlds do not have an alpha channel QuickDraw does
preserve the bits in the unused byte, but you will need to address
the issue of setting those bits yourself somehow.
No, it doesn't.
QuickDraw will often, but not always, zero out the unused byte (and in
some operations, do other things to it - for example, there are times
when CopyBits will copy the extra byte from the source to the
destination, and times when it won't)
