Definitely. "use Carp" and "use warnings" are not as related as it
may seem. "use warnings" is a pragma that controls the warnings
issued by Perl itself, and "use Carp" allows you to issue a warning
(or die) from perspective of caller. That is the message will contain
the filename and line number of the call to your function, not of
some line in the function itself.

Depends. If you want to say the user of your module did something you
don't like you should use carp(), if you fail doing somethig you
should warn().
Depends on where do you want the "user" of your module to look.

I guess you mean
use Carp qw(carp);
yes, you may do that.
