Hmmmm . . . . magic, maybe?
3. If gravity in a system is always twards the star in any given system, (referencing my first point) how come I havn't fallen into the sun?
Because fortunately, you're wrong!
Gravity in a system is NOT always towards the star. That has nothing at all to do with it.
All matter/mass has the property of gravity. Big things have more than little things. So yes, you're being pulled toward the sun by its massive gravity. But you're also being kept down here in Earth's gravity well by this planet's huge mass.
In fact, you are actually attracting Earth and the Sun toward you a little bit, too. But that effect is too small to notice. It's the same reason that close binary stars appear to orbit around a common point, rather than the smaller one orbiting the larger one. They are both attracting/attracted to each other.
