So, does anyone happen to know whether it makes sense to have both the postscript and opentype formats of a font? I'm a web and graphic designer, and know much less about the graphic design side of things (although I want to learn).

I get the general idea that some design firms are heavily invested in postscript for printing purposes, and opentype can come in two flavors - postscript and truetype (if someone can also explain how to tell which is which, I'd appreciate it). It all makes my head hurt, though. Any opinions?

Generally if you own Pro fonts, it's best to use OpenType, because OpenType has several advanced features such as extended ligatures and optical sizes.

OpenType can encapsulate both CFF (PostScript fonts) and TTF (TrueType Fonts) glyphs so theoretically you can change the extension of an OTF font to TTF and it should work properly if it is an encapsulated TrueType, however this is quite unscientific and it might not work all the time.

The best way of testing the format of a font on OS X is to open Font Book, select the font and select Preview Menu > Show Font Info. I do not know for Windows, and in Linux, if it does not open in OpenOffice, it is OpenType CFF (a sign of the sad state of fonts in Linux...)

To sum it up, the best choice for font format is OpenType, it is smaller than the comparable Type 1, it is multi-platform, it supports more language features and is possible to embed on webpages using @font-face.

On OS X Leopard, OTF is as good as AAT, and on Windows, it is a vast superior choice than plain TTF, though support for advanced features is lacking on normal apps (non-professional), you'd have to wait until WPF takes on.

Hope I have cleared your doubts, and if not, feel free to ask.
