As far as the North/South vs East/West question goes, if you know where
you want your signal to go, then you should absolutely orient your
dipole broadside to that direction. If you don't know where you want
your signal to go, or don't yet care, then do what people typically do
and put it up in whichever direction is most convenient. If you've got
the money, the time, and the space, you can always set up two of them at
right angles to each other and switch between them, depending on which
one brings in the louder signal.
As far as making it straight goes (I think that's what you're asking, if
it's not, then please correct me) then as long as the legs aren't too
close together it won't have a huge effect on the radiation pattern. A
right angle is probably not "too close". I don't believe that the
radiation will be substantially less efficient, but you may get the
energy directed in a peculiar direction. The thing is, unless you know
what you're trying to achieve, the thing to do is to put something up
and see what you get. If you find that you communicate really well to
nowhere you want to talk to, then consider making changes or even trying
your hand at some modelling to see what it's really doing.
The thing to understand is that all antennas interact with the
environment that they're in. That means that unless it's well isolated
from nearly everything your signal will go off in weird directions
because it's near the metal in your house or a shed or a fence or
whatever. Trying to anticipate that is of limited use, and probably not
worth the effort until you know what you're trying to do.

Setting up a inverted V multiband dipole 30 feet in the air and was
wondering should I orient the wires to begin with so broadside to the
dipole is North and South or should I orient it for East and West
broadside? I do know that broadside is where most of my signals will
come from...or does it really matter?? Also usually one sets up
dipoles wires so the combined asmith is close to 180 degrees. Can I
do a 90 degree combined asmith...... or will that decrease my signals?
Thank you for your thoughts guys, I appreciate it!
