If you go for Jackson supercharger you won't have to worry about either, since the supercharger replaces the intake manifold and throttle body.
If your looking at turbo, check into the intake manifolds with individual throttle bodies, but they are a bit pricey, and probably not worth it especially since your going turbo.
I agree, unless you have extra cash, stick with stock throttle body but go for a high flow intake manifold. At the very least port your stock manifold so that the turbo can force more air down your engine's throat.
