Hi Friend,
"Cisco 3560 L3 switch" is an advanced device from cisco. It
can do inter vlan routing by itself. Instead of providing
the step by step information, I recommend you to refer the
simple configuration provided in the below weblink. Hope
that will help you to understand the concepts thoroughly.

If you want inter Vlan communication between different VLANS through a Layer 3 Switch you dont need to create Sub-Interfaces..Instead you create SVI's (Switched Virtual Interfaces)..
In the above eg. to create SVI's for VLANs 2,3 and 10 try this -
(config)# interface vlan 2
