sectioningsmall-caps
When I try to do something like \section{Heading with \textsc{small caps}}, the compiler complains with "LaTeX Font Warning: Some font shapes were not available, defaults substituted." and replaces the small-caps with normal test.
Any suggestions on how to fix this?
I'm wondering which font packages are available in MikTeX and TeXLive containing real small caps and also work together with the "microtype" package? ...
kpfontshas real small caps but doesn't work withmicrotypeas it complains that it doesn't work with non-scalable fonts.
As others have pointed out, the fact that you're getting this error message is not because of some fundamental incompatibility between the two packages, but because your document's preamble instructions must, somewhere, be loading the font in OT1 encoding. Finding the offending instruction and replacing it with a command such as
\usepackage[T1]{fontenc}
should do the trick.
By the way, version 2.5 of microtype, available in beta form from this site, coexists just fine with xelatex. The package's "official" version on the CTAN is still 2.4., which unfortunately doesn't work with xe(la)tex. I've been using version 2.5 for more than a month now without experiencing any problems when using xelatex.
I believe there are quite a few latex packages that provide fonts with "real" small caps and also come with matching math fonts. Among them are (with no claim whatsoever to completeness!)
\usepackage[sc]{mathpazo}There is also the fourier package, which uses a font that's based on the Adobe Utopia text font (generally classified as a "transitional" font a la Baskerville). To get "real" rather than "faked" small caps with this package, you'll have to have access to Adobe's (non-free) Utopia font; if your system already happens to have this font, you may want to consider it too.
The problem is that your font does not define a bold small-caps. If you use a font with a bold small-caps such as Minion Pro, it will work:

The standard Computer Modern fonts don't contain bold small caps. You could use the CM-Super fonts instead; add to the preamble
