Hey uncleslinky.
Check out Paco de Lucia, Rumba Tres, Gipsy Kings.
As for scales, get acquainted with the Phrygian and Phrygian Major among others Scales.
And as for techniques practice finger-picking and what we call in Spanish Rasgeo or Rasgueado.
Hope that helps.
P.S. Take a listen to my favorite song by the Gipsy Kings “Viento del Arena”
