Yes, rsync will send the complete file list each time it runs. It seems
odd to me that building the file list would take 15 minutes; when I back
up the system partition of my computer (300,000 files) rsync takes
perhaps 5 minutes to build the file list. I don't think using several
points would be better or worse than doing it all at once, just more

The third filter will match /binbackup/bin/foo and cause it to be
excluded, which isn't what you want.
You can do this:
That way, the third filter does not
exclude /binbackup/bin/foo. /binbackup/bar/baz is technically included,
but since /binbackup/bar is excluded, rsync never even goes inside it.
Or you can do this:
The second filter overrides the third one and causes /binbackup/bin and
everything inside to be included.
