Don't know if there is any command to display queue limit of an 
interface, but an empty policy map will help you. Just attach it to 
the interface. Just now I've test it on GE port, the default queue is 
the same - 48 packets.
Look also at the page:
http://cisco.com/en/US/products/ps6580/products_configuration_guide_chapter09186a00808de1e9.html
You can find there many configuration examples and also notes about 
platform limitations.

About 3560's I don't know too much, they have only limited QoS. Try to 
find some command of show mls qos ... to display queue sizes, browse 
the documentation or wait for someone to reply in this mailing 
list :)
