Don't think the shaft is turning just the gear rocking. I did just replace the seal and housing gasket. Anything to worry about or did I screw up something?

There should be a dowel pin in the shaft that the gear slides onto that fixes the gear to the shaft. There should be no play at all between the two.
If you have a plastic gear then the center may be starting to break loose...

Yes, especially if the bolt was snot as tight as needed.

If it has 1/8" radial play (left and right, or up and down) then it sound like the front auxiliary shaft bushing is very worn.
You should not be able to feel any play, the bearing clearance should be a few thousands.
The front intake camshaft bearing is lubricated through the aux shaft front bearing, so if you have that much play in the bearing than likely that cam bearing is not getting any oil.
