Hi Dallan
"1. For step 1, you added keyframes to animate the zooming into the centre? ..."
Yes. keeping the AR at 16:9 (If that's what you have, just set the first keyframe at minimum zoom.(All the frame) Slide the effect red cursor to end of the image clip (right hand end) and close zoom down to as small as possible. You can either monitor this in an enlarged clip preview or pull the ends of all four graph lines down (the orange keyframe markers) so that they are all together at the right on the centre line. The preview should show a zoom in to the very centre of the frame.
"2. Near the end when you say "once through the timewarp (zoom)...: do you mean once the zoom effect has stopped zooming in further and so we would be looking at a more or less still image? .."
Yes...As it was just a test here I used the same starfield image but better still use a different one..After all it's presumably meant to be a different place in space. You could even add a planet, or use a planet surface...The first image zooms in and becomes the second image. I suggested a colour change to show it was "somewhere else"
As it's a sudden change try putting it on a higher track (shift the cockpit up to the top of course) and then use transparency or a short fade-in to make it appear more gradually as the zoom on the lower track ends. Playing around with these things is an excellent way of learning the program.
"2. Where did you get that star field image? It looks awesome. .."
There are many thousands of such images on the web.. Try here....These are in the public domain...

"3. Are there copyright issues if using the NCH audio clips? .."
No. They are available for you to use. For fun you could even record your own by saying "Schwooooooooooo" for the right length of time. 🙂
Have fun
