3D objects are created with lines on special layers that surround parts of objects. The line width defines the height of that part, so these parts have to be of uniform height. Also, it is not possible to create parts with some space between them and the circuit board (like an angled pin connector for instance).
Yes, it's quite a hack :-)

With Eagle 6 the file format was changed to XML. Since these are text files, it is possible to use SubVersion for instance to keep track of component libraries that are used by a team of several people.
There's one very nice feature in newer versions (I don't know since when): Variants. Of course its main purpose is to maintain several variants of one circuit board, but it's still useful if there is only one variant. With one simple menu you can show or hide all these components which will never be populated on the board (like the little caps that are there just in case the thing starts to oscillate). While hidden on the board, in the schematic they are still there, but they are crossed out. I like that feature a lot.
You can also create a BOM with separate columns for the variants.
