Does it matter if the two systems that need public IPs have
(1:1/Server) NAT in front of them?
I assume by "typical NAT translation" you mean individual ports?

This is how we have our DMZ setup

* Public IP block: x.x.x.64/29
* DSL Router is configured with IP x.x.x.65/29
* pfSense is x.x.x.69
* pfSense has ProxyARP VIPs set up on x.x.x.66-68
* Server NAT to push x.x.x.66-68 through to the appropriate server in the DMZ.

We do things a bit differently for our other public IP block
(x.x.x.216/29), it's purpose in life is to allow us to temporarily
expose internal systems on public IPs for interop testing with remote
vendors (we're a small software development firm).

* pfSense LAN interface has an alias assigned to it in the public
block (x.x.x.217)
* firewall rules are created to allow appropriate access from
x.x.x.216/29 to WAN
* firewall rules are created to allow appropriate access from WAN to
x.x.x.216/29
* clients are configured with an IP from the block and a default
gateway of x.x.x.217

Assigning the alias to the LAN interface is a hack, it's not supported
through the WebGUI, details are in here;
