When you run an autodiscovery task, you can assign a monitoring template to it, so all the new discovered devices are automatically created with the checks from the template you used. This includes all kind of remote checks such as ICMP, SNMP, WMI... as far as the devices respond and are compatible with those checks.
This is different from manually creating the agent and creating some individual checks (modules), so yes, you can set some default monitoring for all the autodiscovered devices.

The Enterprise version has in fact some major improvements on this respect. Take a look at the policies here: http://wiki.pandorafms.com/index.php?title=Pandora:Documentation_en:Policy
