I export all my work directly from the Premiere timeline, and have not had sync issues. I will make an export for each format needed, so if it's going to Blu-ray, it is exported specifically for that. If for YouTube, I export specifically for that, and so on. I've used AME a time or two, and it was the same quality result, so I don't think it matters there.
Actually, I seem to recall having one instance of audio exporting out of sync, but it was my fault. I believe I chose the wrong mux setting. There are a lot of settings, and it's easy to mess something up now and then. I'm not saying this is what you did, but make sure you don't have any conflicting settings there.
I know with FC audio sync issues were frequently due to not using 48k sampling rate, and/or using mp3s - is it the same with PP or does 44.1k work well? (adjusting to new workflow)
All my stuff is 48k. Any material I get that isn't, like audio CDs that are 44.1k, I convert in Audition/Soundbooth to 48k before importing it in Premiere so I don't have to worry about it later. It works well for me... hope that helps!
The sampling rate will not have any effect on sync (or at least, with properly functioning software, it shouldn't). And in the case of PP, it doesn't. You should be fine using any 44.1K file in any sequence.
Now, the use of .mp3 files can sometimes cause issues. Go ahead and try them out. If it works, great. If not, convert to Uncompressed.

What specific version? We're up to 5.0.4 now.
There have been bug fixes for audio/video synch in the updates. One of the fixes was for a bug in the conforming of audio and indexing of MPEG files, so you need to delete your media cache files and let Premiere Pro create new ones for this fix to take effect.
Ah very cool that they've address the issue in updates. I just installed Premiere Pro on my new Macbook Pro and then updated to the most current version. When I had that initial problem it was months ago so I think it was right when CS5 came out.
