Here's what I'm using to figure what a complete Lego Pneumatics equipment/parts inventory would look like:

the Lego education website has all those parts except for the distribution block and single port cylinders (the distribution block allowed one to lower the pressure in the single port cylinders to make them retract). The distribution block and single port cylinders were replaced by the two-way switch and two port cylinders which are better and allow for simpler pneumatic circuits. The compressor seen in the second link is just a small pump connected to a motor and the pressure switch is just the small cylinder and an electrical toggle switch with some rubber bands to adjust the amount of force (and thus pressure) required to activate the switch. Everything else is available and would be considered a full set.
