The cron script can be set to send a report via e-Mail, setting the
variable SEND_MAIL_ON_NO_ERROR to yes will setup a mail address for all
jobs. Now on my 64bit machine this variable turned up in YasT in
system-->/etc/sysconfig Editor but it looks as if was placed in the
/etc/sysconfig/cron file because I was using it on the system already.
You can try adding the line

SEND_MAIL_ON_NO_ERROR=yes

in the /etc/sysconfig/cron file, or add the line to the
/usr/lib/cron/run-crons script. This is a bit of pain because you get
messages for the hourly cron jobs and I run a modified run-cron script
that only does this for daily or monthly cron jobs. (Thinking of
modifying it further to send a daily digest plus error mails).

Cron does some basic syslogging ... but nothing very detailed.

This is a lock file... If there are executable files this file is
created for each of the cron.<time> directories. To force the daily
scripts to run  use touch to create the cron.daily file at least 24
hours before the current time. Otherwise it will effectively block
exuction for 24 hours.
