you can adjust the air/fuel with the tuner but you need a wideband to actually see your air/fuel ratio.

As far as the Air/fuel mixture, guess I'll have to get a tuner.
With an N/A car, how lean can I go without damaging anything.
I know it goes by numbers, higher the number is, makes it leaner, correct?

A tuner is only going to allow you to adjust, to properly read and be able to make adjustments, you need a new A/F gauge. You need to get a wideband, you'll know which ones they are, they usually have a digital readout on them as well as the spectrum you have on your current gauge, and they cost around five times as much.
