Advice on creating a multi-subnet network

[mlchris2]

I'm currently running a small multi-subnet network. Here's pretty much how i have the network setup;

*corp server and network: 10.0.0.X/ 255.255.255.0/10.0.0.1
*corp pc & printers: Same As Above
*corp wireless(private): Same As Above
*corp wireless(public): Same As Above
*corp test network: 10.0.3.X/255.255.255.0/10.0.3.1
*colo network: 10.0.1.X/255.255.255.0/10.0.1.1

I am running out of workstation IP's and wanted to seperate the network out as follows;

*corp server & network: 10.0.2.X/255.255.255.0/10.0.2.1
*corp pc & printers: 10.0.0.X/ 255.255.255.0/10.0.0.1
*corp test network: 10.0.3.X/255.255.255.0/10.0.3.1
*corp wireless(priveate): 10.0.5.X/255.255.255.0/10.0.5.1
*corp wireless(public): 10.0.4.X/255.255.255.0/10.0.4.1
*colo network: 10.0.1.X/255.255.255.0/10.0.1.1

I have 2xCisco2651 routers that connect the colo and the corp office. I also have HP Procurve2650 Layer3 switches. Also all servers are 2k3, running AD

All devices are Static IP addressed, except for the pc's. I have several options and i wanted to get a 3rd opinion...

--Option 1:--
re-ip all CORP servers, networking equip, wireless AP's. Keep same MASK. Create a VLAN in Procurve for new subnet. Create a IP route in each Cisco router for each new subnet

--Option 2:--
use Cisco Secondary IP addressing feature and assign a second IP address to the Ethernet adapter on each Cisco. One question I have is... Can I assign more than one secondary IP address to a Ethernet adapter? My corp side will in turn need 5 IP's.

--Option 3:--
Implement a Class B subnet, thus re-ip all devices, but not having to do anything with any VLANs.

--Option 4:--
something else

I would appriciate your feedback. I thought this was going to be a easy project, but as I dove into it, I realize there was few things i didnt think about it.
