Well, the Pango documentation seems to be the best stuff available.

There is a DocBook formatted guide that Havoc Pennington wrote up and
posted to the devel list back in 2001. You can find it here:
http://mail.gnome.org/archives/gtk-devel-list/2001-September/msg00171.html
It was intended as a quick guide to assist in porting GTK+ 1.2 apps to
GTK+ 2.0.
It gives a nice intro to PangoFontDescription and PangoLayout.

Basically, a PangoFontDescription takes the place of GdkFont for font
selection. Pango does not use XLFDs in its interface,
but instead uses a much simpler and saner specification. 

For determining size of rendered text you will probably be interested in
pango_layout objects, specifically pango_layout_get_extents.

The relevant parts of the Pango docs are Basic Pango Interfaces/Fonts
for PangoFondDescription and Basic Pango Interfaces/Layout Objects for
pango_layout stuff.
