Yes you need to list the engine and the propeller on the first page of the AMP and their MM
The airworthiness limiting items (section 4 of MM) is a rather newish thing and potentially only EASA. So quite normal you cn’t find it in a 1977 MM.
I would tale the “Continued Airworthiness Programm” as maintenance recommandation. So you could decide with justification to increase intervals / not do them.
But that where knowing the person/organisation who is is going to sign the ARC is worthwile. So you know what kind of interval aleviation or what kind of justification they are ok with.
