Question: When Marty suggests (in 1985A) that they go back to 2015 to stop Old Biff from taking the almanac in the first place, Doc says no because it'll be 2015A instead. When Old Biff went from 2015 to 1955 to give himself the almanac, when he came back to 2015 again, it was still the same one he left because Marty and Doc are just getting Jennifer out of the new McFly house when he returns. So what's the difference? If Biff can go from 1955 to 2015, without it becoming 2015A, then why can't Marty and Doc do it from 1985A?

Answer: The implication is that Biff returned to 2015 before the consequences of his younger self's actions took effect. Biff would have returned to 2015 immediately, as he wouldn't want to risk Marty and Doc discovering that he had stolen the DeLorean. By the time Marty and Doc travel back to 1985, the consequences of Biff's actions have solidified.
Answer: The reason Biff arrives like that is because Lorraine found out that he murdered George and shot him.
Where did you get that from please?
That info is reported to be from the audio commentary to a deleted scene, published on the official DVD. Since the scene has been filmed, it might even be considered canonical (as opposed to ideas from the drafting stage of the script which, ultimately, were abandoned).
Are those tidbits of information, such as this DVD commentary track, considered canonical?

Answer: There is a deleted scene on the DVD that answers this. You will notice that when Biff returns to 2015 it appears as if he is dying, on the deleted scene when Marty and Doc leave 2015 you see Biff vanish which suggests the "ripple effect" of Biff giving the Almanac to his younger self places everyone in an Alternate 2015 which Biff is no alive to see so is erased from existence. I have seen somewhere a suggestion Biff was shot in 1996, chances are with Biff gone by 2015 Hill Valley may have been a more peaceful city again. Hilldale was a run down suburb in the original 2015 and could have been the same in an Alternate 2015, we never saw inside any houses at that point to answer where Marty may have lived in an Alternative 2015 but perhaps in Switzerland.
