As for the latter I've found Cacti to be very useful. IP SLA templates
can be found here:

Setting up the IP SLA probes themselves are IMO quite straightforward.
If you need to manage a large number of probes you do want some kind of
tool to automate creating new ones of course. We currently script it via
crude templates, but we don't have that many.

As you're probably aware, the 6500 supervisors (and other switches) have
lousy processors. You may not get good results with many IP SLA probes,
especially if they're supposed to measure latency and/or jitter. We use
2801s instead.
