Unless there is something I'm missing in your pictures, the paint looks good to me! It appears shinier and smoother than most of mine before clearing. What you will need to be careful of is the "trim" an hinges both when polishing or sanding.
The krylon clear comes out fine to me. Not as fine as Tamiya does, but you wont have to worry too much with globs coming out.
I will leave others with more experience to try to answer your questions better,
