I believe that Category:Archie Comics characters is similar to Category:Pre-Super Genesis Wave characters (based on your edit on the T-Pup page), so it isn't necessary.

For your second question, I would prefer Category:Crossover characters.

Note that this is only based on my opinion, please ask Ultrasonic9000 for the final decision. :)
