What a gorgeous Vette! Nice job resurrecting this one, the paint is great and the interior too.
However, as far as the bubbles in your rear lights, there isn't much you can do. The last time I did this, I ended up having to yank the lenses off, clean off the glue with a wet Q-tip, and reglue them.
A tip for the future: With Testors clear parts cement, only apply glue around the edges of the parts to glue, and any squeeze-out will dry invisible.
