About the "echoes" of people in the Nexus -- I think it's implied that only the El-Aurians have them, because they left the Nexus unwillingly. Here's the dialogue:
So Guinan, Soran and the other 45 El-Aurians would all still have "echoes" in the Nexus because they were "ripped" away, leaving pieces of themselves behind. But Kirk and Picard left willingly, so they separated completely from the Nexus and came back intact -- therefore, no Echo Picard or Echo Kirk.

And then:PICARD: And you were beamed away from there?
GUINAN: Pulled. Ripped away. None of us wanted to go.
ECHO GUINAN: Think of me as an echo of the person you know. A part of herself she left behind...
PICARD: ...when the Enterprise-B beamed you up from the Lakul.
