Runlevel 0 is poweroff. 1 is single user/maintenance mode. 4, well, no one actually uses 4. And 6 is reboot. So, once the network's up, text mode and X-mode.

"on" defaults to enabling it in runlevels 2 through 5
Evidence in the Red Hat docs on chkconfig [0] in section 11.2.3.2
[snippet] 11.2.3.2. Enabling a Service To enable a service in runlevels 2, 3, 4, and 5, type the following at a shell prompt as root:
chkconfig *service_name* on
For example, to enable the httpd service in these four runlevels, type:
~]# chkconfig httpd on
To enable a service in certain runlevels only, add the --level option followed by numbers from 0 to 6 representing each runlevel in which you want the service to run:
chkconfig *service_name* on --level *runlevels*
For instance, to enable the *abrtd* service in runlevels 3 and 5, type:
~]# chkconfig abrtd on --level 35

The - means that it is not enabled. The 2345 means that it gets started in run levels 2, 3, 4 and 5.

That's what one would think from the docs, but in fact in both cases the service is started in run levels 2, 3, 4, and 5.

The I Think the key word is _default_. From the man page:
If the service should not, by default, be started in any runlevels, a - should be used in place of the runlevels list.
So _by default_, mysqld is not started in any run level. If you run 'chkconfig mysqld reset' with the initfile data you show above then mysqld startup should be disabled, just as if you had run 'chkconfig mysqld off'. If instead the string '2345' appeared there instead of '-' then _by default_ mysqld would start.
Think of it as controlling the fresh-out-of-the-box on/off state of the service in question. Make sense?
