VLAN for Voice on Cisco 3750

Please bear with me. I may be asking a simple question but the bottom line is I need some help.

I have a single Cisco 3750 POE Switch  (10/100Mbps) and a Cisco 2901 Router (CME).

My data network is on 192.168.5.0/24 (VLAN 500) and Voice on 192.168.4.0/24 (VLAN 400). The DHCP Server is on a WIndows Server (192.168.5.4). The CME router is on port 2 (int F4/0/2), the DHCP on port 3 and the firewall (192.168.5.1) on port 1. the user computers connection to the network via the Cisco 7945 IP Phones.

I would like to Configure the VLAN for VOICE and DATA including interVLAN routing.

I would need some sample configuration to help me started.
