Thanks a lot for the detailed reply, and I will clean up the first post in a bit with your suggestions. I just got back from an extended trip back home, during which time I did not have japanese fonts installed on my computer, so I have been unable to reply until now. I know that when I was beginning to study, these kind of expressions really bothered me and I had trouble using them, so I hope that this thread will get some more hits in the future.
About ひびき--is this a word that would be better replaced in almost all cases by に聞こえる? I have only come across the word once, and that was in a book, so I don't know how natural it would sound in conversation.
