| Are there any rules regarding the use of "about". |

There aren't any rules concerning
about in particular. It's a preposition, of which there are many.
The
about in this sentence goes with
confusion.
There is a great deal of confusion about this phenomenon.
Different nouns go naturally with different prepositions. You need to learn each combination separately.
In addition to
confusion about, there's
awareness of,
relationship to,
dependence on,
confidence in, and thousands of others.
We had no awareness of the situation.
This has an interesting relationship to the problem.
They showed great confidence in their teachers.
________
With regard to
whether, it is simply the marker of an indirect
question structure, specifically a yes-no indirect question.
Other markers are the question words
what, who, how, where, when,
etc. Such structures can take the place of nouns, so in addition
to their uses as subjects and objects, they can be used as objects of
prepositions.
We had no awareness of [the situation].
We had no awareness of [whether the situation would change soon].
We had no awareness of [how the situation might change].
We had no awareness of [when the situation might change].
This has an interesting relationship to [the problem].

There has been confusion about [how this matter could have become such a problem].
There has been confusion about [where we can get more information about this matter].
There has been confusion about [whether this matter has been resolved].
Hopefully, that answers your question about whether these structures are correct.
