To create VLANs you must first enter the vlan database command at the privileged exec prompt. That should move you to the Switch(vlan)# prompt. You can then set up your VLANs with the vlan xx name yyyyyy command where xx and yyyyyy are the vlan number and name respectively. See Creating VLANs on Catalyst Switches for more information on assigning ports, etc.
