The 'amoeba moving' your seeing is probably the boundary layer. Thats the layer of air sitting on top of your main mirror. How turbulent it is shows how cooled down the main mirror is.A really warm mirror will show a lot of movement.
There are ways to remove the layer, maybe someone here has worked on removing the layer on the gs scopes and can jump in with their thoughts.
The 'crosshairs' are the diffraction spikes from the spider.There is no way to remove them apart from replacing the straight spider with a curved one, even then your only spreading them out , not totally removing them.
Use as high a mag ep as seeing will allow to startest. You should have still seen the rings with the 9mm.???? Maybe not perfectly but enough to show you the line up of your optics, which is what your after. Keep the star perfectly centred while assessing the startest. On a good night you can determine the finer details of your optics. A lot of which you cant do anything about.Theirs a link on another thread with some details of startesting with pics.
Your tails are gone so thats good. Reducing the ugliness of the image makes it all worthwhile.
