Good for you! Great plan.
[QUOTE=stewie8787]
say i want to build a A major scale i use the "ws ws hs ws ws ws hs" theory and say start from the A on the 5th string and then i drop a string after 3 notes and bring it up 5 frets and so on and so forth, does that work for all major scales no matter what key?

Yes. :)

The formula is the defining characteristic of a scale. Pick a root note, put the circled 1 of the scale pattern on that note, apply the proper whole step, half step formula to the fretboard and you are on your way.
