Way back we used zaxworks invigorator (dumbest name in the world) when it was a maya plugin. When they discontinued the maya version, we kept an old version of maya lying around, purely so we could run invgorator for importin and bevelling illustrator files, nothing else came close. I don't miss motion graphics, but I miss that plugin.
As others have said, I remember last time I suffered through bevel plus, we had to grit our teeth and go through all the options on illustrator export until we found one maya was happy with. Going back several versions of illustrator compatibility, stripping out any extra special sauce from the illustrator file itself, the pdf compatibility thing Anthony mentioned sounds like a good tip.
Beyond that yeah, it's horrible Gary, I feel your pain. :)
If time is of the essence, grab a 30 day demo of cinema4d and mesh it in there, then bring it to maya. Its built in illustrator support is good, but the cineversity artsmart plugin is distressingly good, does in seconds what'd take you hours in maya.
