KCHD to KMYF

I actually do have a question for the knowledgeable people here
though.

I'm still a newbie student pilot, so don't have a bunch of
experience. Out here in the midwest we don't have a bunch of the
restricted airspace like apparently out in the desert. Especially the
ones in question here that look like heavily clustered, and ranging
from 0 AGL to 80000 MSL. When calling the controlling agency is it
typical to be able to ask clearance into them all of them at once? Or
must it be done piecewise. Any risk of getting cleared into some of
them, then getting told the next is 'active' and having to adjust for
it? Could be problematic especially for the clustered restricted like
2306A, 2308A, 2308B, etc.

Is it typical for these clusters to have two different controlling
agencies? Probably not I hope.

Seems to someone like me not used to dealing with confusion like these
heavily clustered areas that it would be a pain to deal with.
