So long as you're confident that you have actually downloaded the
sources from the RELENG_9 branch, then you can be confident that the
system version will be one of those -- at the moment, you'll get 9.0-RC1
but over time this will eventually change to 9.0-STABLE.

The file you want is /usr/src/sys/conf/newvers.sh  This is a script that
edits version information into various source code files.  The bit you
need is near the top of the file -- just following line 33:

    33	TYPE="FreeBSD"
    34	REVISION="9.0"
    35	BRANCH="RC1"
    36	if [ "X${BRANCH_OVERRIDE}" != "X" ]; then
    37		BRANCH=${BRANCH_OVERRIDE}
    38	fi
    39	RELEASE="${REVISION}-${BRANCH}"
    40	VERSION="${TYPE} ${RELEASE}"
    41	SYSDIR=$(dirname $0)/..

Unfortunately the value want is RELEASE, which is assembled from parts,
so not trivially grep'able.  But you can easily see the REVISION is set
to 9.0 and BRANCH is RC1 so the whole things comes to 9.0-RC1.  Simple.

No -- you shouldn't need to worry about that.  The name
'releng9-supfile' you chose doesn't match anything produced by the
system, so it won't be overwritten.  (Not that you shouldn't keep a
backup somewhere -- that's only sensible.)

Hmmm.... actually you have highlighted a small omission in the
procedures for branching RELENG_9 and RELENG_9_0 -- the cvsup example
supfiles  /usr/src/share/examples/{stable,standard}-supfile should be
updated to match the branch they are installed from.  In your case both
of those files should use the RELENG_9 tag, but that hasn't been
commmitted yet.
