Yeah sounds good. Also, make sure to set the stepper driver voltage to the value in your manual before printing.

You probably won't need to measure e-steps for your first print, you can use the default settings in the files Colin provided for your first prints and it should come out just fine. Just something to cut out if you're looking to get printing asap

A few tips on what held me up when I built mine:

If you find your X axis is going the wrong way (towards the stepper motor) when you home your axes in pronterface for the first time, just flip the stepper motor connector around on your RAMPS board.

Use something thicker than a sheet of paper like a guitar pick or thin stack of post-its when you first try to level your bed. In addition to adjusting the 3 leveling screws remember that you can also adjust the z threaded rods in case your z axis isn't level.
