How can I tell when an Active Directory replicates? I am trying to verify against a graph I have

If you mean realtime when it is replicating you can watch the queue
(repadmin /queue or adqueueloop which you can find on my website's freeware
page). AD is constantly doing replication work in the background, If you
just want to know the last time it replicated a specific partition you can
look at the repadmin /showreps output.

Is there a reasonable Perfmon counter(s) to watch to indicate
replication activity?
replication activity?

The one I tend to watch is DRA Pending Replication Syncs (In NTDS counters).
It shows you the queue count of the thread that does the inbound
replication. This queue should be coming back to zero every x minute period
where you specify that period. It means that the queue is not completely
backed up and is getting cleared. Usually the period is based on the time
schedule of your site link connections. So if you have 15 minute site link
connections you should be seeing the queue go to zero at least once every 15
minutes. If it doesn't it means your replication is being delayed across
replication cycles (i.e. you aren't replicating every 15 minutes like your
think and eventually will snowball badly).
Note that there is a bug in some of the post SP3 hotfixes that got fixed in
SP4 for this counter. The bug was that things would get queued up and the
counter would be incremented but then the replication system would realize
it was duped request and would pop the item off the queue but wouldn't
decrement the counter. That was kind of annoying when I found it but MS
tracked it down within a couple of weeks once I alerted them and fixed it.
