Some of those questions you asked have no answer. At least not without knowing power goals, and class rules.

Technically either a T4 or T6 will do it, divided or not. Either 2.25 or 2.5 will do, 2.25 will spool faster.

With an open housing you could do with a single large waste gate. For a true divided setup youll need 2.

Get a custom camshaft spec'd for you. There isn't a magic 'USE THIS' answer to all of these questions, or else nobody would ever have to ask.
