Hi, I've been ask to configure interfaces on my 3560, but they want them as
interface gigEthernet2/0/1
!
interface gigEthernet2/0/2
etc
I only see
interface gigEthernet0/1
!
interface gigEthernet0/2
This "2" I assume is the sub-interface from a trunk? How do I enable this on the switch?

The 3750 displays the naming convention as g x/y/z where the first letter refers to the switch number in the stack, second the slot and third the port
for eg if we have a 3 switch 3750 stack, the ports of the 3rd switch will be seen numbered as g 3/y/z
The 3560 still uses the standard naming convention slot/port where slot would be moslty 0 since it is non modular
I am afraid you cannot get the 2 prefixed on the 3560 interfaces

I see. I have Cisco ASA, it's 0/2 port goes into a Cisco 3750, this provides VLANS for the webservers etc, off the 3750 is this 3560, which I want to add 2 more VLAN's, how can I do this?

Sorry i am not able to correctly follow your question
If you want to create vlans on the 3560, you can configure your 3750 as the VTP server, create a trunk to 3560. This will ensure all the vlan information is shared between the switches. The SVI's can then be defined on the 3750
assume the connectivity as 3750 -G1/0/25 to 3560-G0/1
on the 3750
conf t
vtp domain cisco
vtp mode server
vlan 2 name newvlan1
vlan 3 name newvlan2
interface vlan 2
ip address
no shut
interface vlan 3
ip address
no shut
interface g 1/0/25
switchport trunk encap dot1q
switchport mode trunk
on the 3560
vtp mode transparent
vtp domain cisco
vtp mode client
interface g 0/1
switchport trunk encap dot1q
switchport mode trunk
This will replicate the vlans. Now assign the ports to the respective vlans as per your need
interface fa 0/1
switchport access vlan 2
interface fa 0/2
switchport access vlan 3 etc etc
