Having the knowledge of how the piano keyboard is laid out puts you ahead of someone who does not. When I started I referenced everything to the keyboard because the sharps and flats are shown different than the natural notes unlike the guitar fretboard where 1 fret is identical to the next fret. ( I sometimes thought about painting the frets white and black to match a piano. of course it would get out of whack if you got away from standard tuning)
When you get to working with keys and scales you'll find it quicker to do WWHWWWH (major scale where W = whole step and H= half step) on the mental image of your keyboard than anyway else.
