comment Is gauge invariance essential to a theory be renormalizable?
If you remember th procedure of renormalization, the gauge invariance that we require of the lagrangian imposes constraints on the renormalization parameters.

And yet it conveys the point that renormalization is not related to gauge invariance.

comment Scalar QED perturbation theory
I did, I look for a comprehensive text-book treatment. The notes on google are no "high quality". Specific to scalar QED is the derivation of feynman rules and diagrams.
