Hello Bill,
Welcome to the CDR forum.
Integration of CDR, ADR & PhD only began with PD11. There is no integration with PD10.
Personally, I don't see that as a
huge disadvantage. ColorDirector works as a standalone, so you can make your adjustments, produce the clip, then import it into PD10.
On the other question, unless you married to PD10, there are some great features in PD12 (and the asking price is quite reasonable at the moment). It's certainly not necessary unless you prefer the "round trip editing" idea.
