Only need the Hylian shield and 1 bottle in order to obtain all the items in skyward sword. ( I'm not going to bother myself with getting all the heart pieces). Wasted a lot of time collecting bugs only to discover you get a bug medal later on in the game, not too mention that near the end even a bug island opens up....
