Hi Ross,

I know this issue is resolved now, but you had a couple of open  
questions about fontspec...

Try instead:
   \setromanfont[Mapping=tex-text]{Lucida Grande}

fontspec uses the NFSS to create font families, so adding font  
features directly using plain XeTeX syntax will confuse it quite a  
bit, which explains the warning given:

Everything is all good with the syntax for \setromanfont shown above.

Cheers,
