First, make sure your working in a 32bit Project. If you are not, you are losing information. (And it's not as simple as what I just said, but at this point, I cant go back to the beginning.)
Your best picture export is an uncompressed TIFF image sequence. If you are talking about final movie with sound, it depends what you are exporting it for: web, DVD, Festival, 35mm transfer, etc.
You can export any uncompressed image sequence (TIFF, OpenEXR, Cineon, etc), or any variety of QT codecs (animation, uncompessed 4:2:2, etc). They're all good enough for DVCAM, as I'm assuming you're not going to film out.
If doing a film out, then it depends on who's doing the film out and what they need.
FWIW: I would do an Animation QT with 48kHz audio since it's a lossless 4:4:4 codec and comes standard with QT so any computer with QT installed can open it. Or an OpenEXR image sequence with audio separate if you want an image sequence instead.
