Yes.

No.

You'll get so much data that you won't be able to make heads or tails
of it.  And profiling is heavy enough that people hardly ever do it on
production servers.

Just pick one type of request that seems slow, make that request on
your dev machine from your browser, and look at the results.  This is
normally all it takes to find bottlenecks.

If you're concerned about finding which things are most frequently
called, just do standard log analysis to find out.
