For RAM startup import _RAM.ecm, for ROM startup import _ROM.ecm. They
set some additional parameters not set by the template.

Yes - but as I said, have patience: there'll be released a RedBoot
port for AT91EB40 in a week or so.

No.

.ecm files are just configuration settings. They are created using the
ecosconfig export option (and similar, if existant, in the graphical
configuration tool).

Don't know if it's needed to put RedBoot in flash, or if there's
already a board monitor there. Wait for the RedBoot release - it'll
have documentation for getting started.
