these discussions also remind me of what I think is (to me) the most clear and unmistakeable way of referring to pleasure -- as "the guide" of life more so than "the good."
It's like that cliche we hear a lot today about how "the journey is more important than the destination."
Pleasure is an experience --- I'd say that the goal of an Epicurean is to experience a pleasureable life.
A non-Epicurean may be focused on the life goal of getting things and achievements, through the abstraction of "virtue" or "being (or striving to be) a good person" or "excellence" or "rising to the top". But this would not guarantee a happy life. So Epicurus says here is the path that he believes will guarantee a happy life. And also important to consider that virtue still does have a place within Epicureanism, as a tool which leads to a good experience --- to give an analogy: one properly tunes up one's car engine so that the car runs smoothly. And another anology: when playing a guitar one properly tunes the strings for the most pleasant sounds, avoiding over-tightening or under-tightening the strings -- so we "properly tune up our life" so that we don't go through life feeling tense, anxious or frought, or lethargic or sleeping all the time -- and this would be important for the experience of a pleasureable life.
