This was discussed at length on this list not too long ago.  You'll see
lots of posts on the subject in the list archives.

The general concensus is that the router will continue to function but it
will complain, e.g. issue warnings that the bandwidth point limit on one
of the busses has been exceeded.

The major caveats are that the router may not function properly if it's
heavily loaded / moving lots of traffic and Cisco may not provide full
support if you get into a situation where the router starts doing weird
things because you've exceeded the point limits.  As always, YMMV.

Yes, the points are determined by the interface card, regardless of how
many ports are actually in use.

It should still count as 400 points.  Shutting down unused interfaces
doesn't save you anything for this.
