I'm not sure what you are talking about wrt guitar and standard notation. Finger (PIMA) indication, staccato/legato, vibrato, tremolo, slurs, hammer, pulls, etc...it's all there. I don't see as much notation around hammer/pull as a classical player, but pick up a classical guitar music book sometime...you'll find that everything (guitar-related) you mentioned needing to be included, is already included.
