"Tone" is the term used to describe any given musical note, but without actually naming it. hence why the term is used when discribing a scale with no root note.
steps and half steps are just a variation of the same term.
as for your scale, let me see if i remember..
the A major scale is like this:
A B C D E F G A, which would look something like this in terms of TAB/Notation:
the second line, is if you move the scale up one tone. its still the A major scale, but in the frygian mode (i think... kinda drunk here, maybe majin you would be able to explain better...). playing in different modes, allows you to stay in the key of A (for example the whole piece is in the key of A) but your scale is now in B, yet altogether in the same key.
its weird stuff, and i dunno how it works completely, but i know that side of the technicalities...
