Sounds like to me.

I definitly want to see a syslog entry for when it runs (with success or not), 
too, so that it shows up in logcheck too.

Not sure how invasive the check is, but maybe even every 15min?

Today (as opposed to some years ago) I dont think /usr should be on a seperate 
partition anymore. I know about the benefits of having partitions per 
service, but with todays terrabyte drives that has become a lot less useful 
and more partitions mean more cognitive stress for system administrators.

is squid configured to use that much space? the default is 256mb...
