It's about the feel of the meat. You can do it by touch. If you take the steak while on the grill or in the pan and squeeze the sides you will feel the amount of give or firmness of the particular meat.
Take you index finger and your left hand. For rare you will poke the space between your index and thumb, the fleshy bit. That will be rare, lots of give very little firmness. For Med-Rare extend and tighten the muscle a bit, it will be firm but have a bit of give. And Med. will be your thumb and index finger almost into a fist. Firm with little give. Med-well is the same as well. Well is just going to be dark and slightly blackened...and disgusting.
The temps (F) will be if you measure with a thermometer:
Rare - ~135
Med-Rare - ~145
Med - ~155
Med-Well - ~165
Well - ~170
There is very little difference between Med-Well and Well as when the meat is cooked the carry over cooking of the meat will most certainly bring it up to 170.
This is applicable to chicken as well. (Cook to 165 of course)
With regards to cooking the meat before grinding it up, not really necessary if you have confidence in your butcher. While the inside of the particular cut is clean as it has never been exposed to oxygen, if the meat is fresh and high quality you can eat it raw (Beef Tar-Tar anyone?). Check the date when it was fabricated (fresh as possible) and if you trust the seller then by all means I say just go for it. Remember that the particular steak you bought came from a whole side or rack and hasn't really been sitting out in the open air exposed to bacteria.
