I don't know why I bother replying, but anyway.
The gate addresses do change with galactic drift. That's why in the Stargate movie they could only connect to a single gate. Normally the DHD takes care of recalculating the address, but they didn't have one on earth.
The ninth chevron is for selecting a location that is even farther away than a single galaxy. The stargate didn't connect to the ship while it was in hyperspace: if you watch the intro sequence, you can see that the ship drops out of hyperspace before the wormhole connects. After the gate was closed, it entered hyperspace again.
