Yes.

Not really... you can use a tool such as FontForge to view the font, or ttx to dump its contents to a text file that will list all the glyphs, but it still may not be entirely obvious which glyphs are used in exactly which contexts, in cases with complex OpenType layout tables.

Another possibility would be to use xetex itself to produce a reference page listing all the glyphs with their names; you can iterate over all the glyphs, printing them with \XeTeXglyph <number> and getting their names with \XeTeXglyphname <font> <number>. Something like

  \font\f="MyFont" at 10pt \f
  \newcount\n
  \loop \noindent \number\n : \XeTeXglyph\n\ = \XeTeXglyphname\f\n \par
    \advance\n by 1 \ifnum\n<\XeTeXcountglyphs\f \repeat

though you'd want to format it a bit more tidily, I expect.

Note that it's possible for glyphs to be unnamed, in which case your only option is to specify them directly by glyph number (or by Unicode value, for each character's default glyph).

Great!
