Would putting a piece of paper with tick marks to indicate the length or distance from a reference point like in tape measuring be enough? If not, what are some of other ways of accomplishing this?
Cut up a small, cheap ruler and attach it to the device along the movement path. A few possible sources are Home Depot/Lowe's where you can get cheap yard sticks or Ikea where you can get free paper measuring strips.

Browse through the Keep the Heat/Thermodynamics thread. We had a lengthy discussion about the definition of granular over there.

So, what's a lever with an IMA greater than 3? I sadly have no idea about IMA. Can anyone help?

IMA basically refers to how much force is put in versus how much force is output. And what Chalker7 said, wikipedia is your friend.
