I'm saving up for a 5- string bas and i was wonder, If a guitar plays an open on the E string, would bass do it on the E or the B, or does it matter?
State the question in a different manner please.
Doesn't matter, its the same note.
Yup. An E is an E. You've surely noticed the way you can play an open A or the fifth fret on the E string and get the same note, for example.Doesn't matter, its the same note.
As has been said, it really doesn't matter much. An open E has a slightly different timbre to 5th fret B, though, so it's all preference.

Never heard it call that, is timbre is the same as "voice" or is it timbre on a single string but voice in a chord?
chord voicing is slightly more involved. IIRC, chord voicings is basically rearranging the entire chord, so you get an inversion of the original chord. You will get different sound qualities or timbres in this way.
