multiple subnet on outside interface of ASA 5510

My ISP has issued me two subnets which each having 5 useable IP's. The first subnet is bound to interface 0/0. I want to bind the other subnet to a virtual interface for I only have one physical port on my ASA plugged into their router. Below is my current interface config. What are the commands to create a virtual interface for my outside interface? ALso, how can I perform a one to one NAT on to an IP address of 192.168.1.12 that is accessble via my 0/1 interface? This one to one NAT being from one of the useable IP's on the new subnet?

ASA Version 8.4(2)

interface Ethernet0/0
nameif outside
security-level 0
ip address xx.xx.xx.xx 255.255.255.248
!
interface Ethernet0/1
speed 100
duplex full
nameif inside
security-level 100
ip address 192.168.1.1 255.255.255.0

Why not simply use the second range on Ethernet0/2 ?

I only have 1 physical interface on the ISP's router. So, I would have to introduce a new physical switch on my end to be able to plug in two physical ports from my ASA into the switch and in return their router into my switch. I do not wish to create a VLAN on my existing switch to place public devices into.. As I understand this is why the virtual interfaces get their value..
