Re: много лет назад ему раассказывал его отец
I would say that imperfective form conveys the process. Depending on the context, it could refer to the process of one single event, or to the process of repetition of the like events.

This sentence describes a process (i.e. continuous, imperfective), it answers the question "what was happening at that moment?" It is about one event merely because we know that one moment is not enough for a series of events to happen.
"В детстве дед [часто/редко] рассказывал мне сказку про колобка" = "He was telling me that story [quite often/hardly any time] when I was a child". This sentence answers the question "What are your most clear childhood memories?", "What did your grandpa usually do?". Such sentence does give an impression that that story was told over and over, many times through my entire childhood. Don't you feel that this sentence is about a habitual, repetitive processes, what with the lack of precise time indication?
On the other hand, perfective form refers to an event. It could be a single event, or an example event of a set, but the sentence itself describes only one event, one instance.
"В 5 часов вечера 12 октября 1982 года мой дед рассказал мне сказку про колобка" = "He told me that story at that specific time". This sentence describes an event, it answers the question "When did you hear that story?" or "What has happened at that time?". One event.
"В детстве дед рассказал мне сказку про колобка" = "It is that story that he told me when I was a child". Actually, the translation heavily depends on the context. This sentence emphasizes one specific event. Perhaps that was a single event, perhaps that was one instance of a repetitive event - we don't know. However this sentence alone is about only one specific event:
"В детстве дед рассказал мне сказку про колобка. И мне так не понравилась лиса, что я уже никогда больше не открывал эту сказку."
"В детстве дед рассказал мне сказку про колобка. Потом я слышал её много раз от разных людей, и каждый рассказывал по-своему."
Please correct my mistakes.
