where the ball lands

Was at the driving range last night trying to sort out my swing, got it a bit better, and think my natural shot has a little draw in it. 2 questions really, this one for the future but a draw bias driver wiould this make my shot straigeter or with more draw.

and the other one. 

looking from where your hitting the ball 
from left to right for a full swing how scatted should your balls be? dunno if that makes sence what i mean is im not bothered about distance but say for a high handicapper how much is spread is acceptable 20m?

i know for a low handicapper they would expect the ball to l
and exactly where they are aiming. 

I have been playing 3 years Matt and I still end up going to where the ball wants me to...
