3750 is L3 switch so its no big problem..
You need to ensure ip routing is enabled with command
ip routing
Create vlans between you want to route
interface Vlan10
ip address 192.168.1.1 255.255.255.0
This IP address would be the default gateway for users in VLAN 10
interface Vlan20
ip address 192.168.2.1 255.255.255.0
This IP address would be the default gateway for users in VLAN 20
Now users in VLAN 10 can communicate with users in VLAN 20

Hi
1) Turn on ip routing ie.
3750(conf t)# ip routing
2) For each vlan that you have on the switch create a L3 vlan interface ie.
vlan 10
192.168.5.1 255.255.255.0
no shut
vlan 11
192.168.6.1 255.255.255.0
no shut
etc..
3) For clients in vlan 10 set the default-gateway to be 192.168.5.1
For clients in vlan 11 set the default-gateway to be 192.168.6.1
etc..
4) If all the inter-vlan routing is done on the 3750 you do not need a routing protocol as the 3750 will automatically route between connected interfaces - provided you have done step 1.
