Well, that may not be the best approach.

You should look through your output for places where small-caps
was requested, but not provided properly.

In particular, the first (bold) instance is giving you
lowercase instead of small uppercase.
Being bold, this is probably in headings or captions;
  e.g.  the  'Figure' part at the beginning of the caption.

If that is the only thing that is wrong due to this, then
yes it is nothing to worry about, provided it still looks OK.

The second instance is of sans-serif smallcaps being given
as roman small-caps. This may well look quite bad, to have
roman in the middle of a block of stuff that is otherwise
sans-serif.  But more likely it is another kind of header,
maybe in footnotes, table-of-contents, or perhaps due to
the bibliography style.

Note that the warnings occur the first time that you
try to *use* the requested combination of font styles
and shapes. As source line-numbers are given, you should
be able to read from the log-file which was the data file
being input at that point, and find the corresponding line.
Then determine the font-switching macro that triggered the

If it is near the beginning of your document, there is a
good chance that it happens while reading a .toc, .lof
or .lot file, or other metadata stuff that you place
near the front of your magnum opus, rather than amongst
its mathematical content.

Maybe you have a glossary of terms, inserted near the
beginning of the book?  Are you really getting the font
that you wanted to use for this?

Make use of the information that these messages provide.
They have line-numbers. You can determine the file.
The rest is up to you to check it out.

The .log file is meant to be your friend.
Normally it is, provided you bother to interpret the data
that it contains.
