OK. (I believe this would behave the same under any Mac OS X version.)

Yes, xdvipdfmx often produces more compact PDF (though this can depend on the nature of the document).

This is a problem that started in Tiger (it didn't happen on Panther), and is triggered by the method used to handle .pfb fonts (which Quartz doesn't support). So you see this if using Computer Modern or other "legacy" TeX fonts in .pfb format, but not for TrueType or natively-installed Type 1 or OpenType fonts. The warnings seem to be spurious; the fonts still look correct in the PDF.

Not as far as I know. This is simply how (x)dvipdfmx handles them. Does it matter?
