what difference does the wood the neck is made of make?

and does anyone know any good tele pickups because i dont think the ones with the standard american i just bought are going to be good enough i need an "bloc party" indie kinda sound
an american tele should be fine the way it is for indie music. a maple fretboard has a brighter sound than a rosewood fretboard because maple is a more dense wood than rosewood...did that make sense?
