I would have thought bumping up the clockrate parameter would have had more
effect than changing the bandwidth parameter.

I would say set the interface bandwidth if the default doesn't match
reality and you are using a feature that uses the bandwidth. IGRP, EIGRP,
and OSPF use bandwidth in their routing protocol metrics. I don't know
about your question about bringing up an backup (ISDN) link. Anyone?
So, when might the default not match reality? Serial ports default to 1.5
Mbps even though the circuit could be faster or slower. You could have a
Frame Relay CIR that is less, and you might want your routing protocol
metrics to match the CIR rather than the default, to avoid a route getting
picked as best when it's really not.
I have also bumped up the bandwidth as high as possible in lab situations
or staging areas where I was TFTPing a large file across a lab network that
included a back-to-back serial link.

The goal of the ip bandwidth-percent EIGRP command is to make sure that the
routing protocol itself doesn't use too much bandwidth. Something is
probably wrong if the routing protocol is using 50 percent of the
bandwidth, and just giving it more bandwidth to consume might work, but
might also cause you not to troubleshoot the real problem. EIGRP is
generally a quiet protocol, except for the incessant hellos, which don't
use much bandwidth.
I think the ip bandwidth-percent command got added because of people who
were running EIGRP on unstable networks and on networks with slow links.
When EIGRP converges (during startup) or reconverges (during problems) it
could use a lot of bandwidth on a slow link. I'm sure there are uses for
the command, but I think it's kind of a Band-Aid command.
