If possible, it would be good to get ON Semi versions of these transistors as that is a lineal descendant of the old Motorola Components group.
I had a friend who worked in procurement of obsolete components for a military supplier and he told me that many parts were sold under the same number as "functionally equivalent", but they would find that one would have an ft of, say, 4MHz while an "equivalent" would be maybe 40MHz and cause the old circuit design to oscillate like crazy.
It's certainly not a given, but it's possible that ON Semi parts would have been made in the same fab as your old parts, or at least in one with a very similar process flow.
Impossible to say for sure if those resistor got burned due to the failure of those PNPs, but I'd guess that it's quite likely. Far more common for xtors to fail than resistors, active components are generally more liable to damage to passives (maybe excepting inductors and transformers).
