For item 2 it is available from here somewhere (I have a copy):

Its in the forth set and still available as YwRobot_Breadboard_Power_Supply_v5.fzpz. There are a number of other interesting items in here too (although some of them I couldn't find any more). Adafruit also has a large repository of their parts that they maintain which may have the button you are looking for.
