Alright, I need to pick the brains of my fellow geeks for I failed the CCNA because layer 2 made my brain itch.

Left Image is what my network currently looks like.
Right Image is what I want my network to look like.

The firewall only has two interfaces: WAN and LAN.

On the switch:
Port 1 is the link to the firewall
Port 2 is a workstation
Port 3 is a workstation
Port 4 is a VOIP phone
Port 5 is a Wireless Access Point

Currently, there are no VLANs configured.

I know I have to trunk the port from the firewall to the switch but then what? I can tell the switch that port 1 is going to be a trunk but does the firewall have to know the inside interface is a trunk port? Do I tell the switch that all ports are all part of trunk 1 or should they all be on separate trunks? The switch is an HP Procurve 1800-8G that is not layer 3 and appears to do stuff non-Cisco-y. I don't care about the inter-VLAN routing right now, that should be easy, but I can't wrap my noggin on the nuances of what needs to be done on the switch and firewall.
