Cisco Routers :: RV082 And Public Static IPs And UVerse?

I recently "upgraded" to Uverse from DSL. While the speed boost is nice, UVerse comes with a 2wire residential gateway. Unfortunately you can't disable the DHCP functionality in the 2wire router, nor can you disable the router functionality completely and just run it as a modem, which has pretty much made it impossible to integrate into my network.So the partial solution anyway is to keep using the rv082 (yey!) behind the 2wire, assign a public static IP to the rv082 WAN1 i/f, disable the firewall in the 2wire for the rv082, and up and running again.The problem I'm facing now is that I had 3 devices on the LAN that were published using individual public static IPs. With good-ol'-DSL, I could use the one-to-one-NAT feature in the rv082, block any unwanted traffic in the firewall, and everything works. Unfortunately with the configuration options in the 2wire, I can only assign a single public IP address to any one device hooked up to it, in this case the rv082 WAN1 port.i have the one-to-one-NAT configured sequentially on the WAN and LAN side on the rv082 with nothing else hooked up to the 2wire. For example, one-to-one-NAT configuration in the rv082:
 
WAN range: 66.77.88.91 to 66.77..88.93
LAN range: 192.168.0.2 to 192.168.0.4
 
The 2wire is allocating the first public static IP in the range to the rv082 (i.e. 66.77.88.91). This works 100% reliably for this address - however because I can only assign a single address in the 2wire interface the other devices are no longer accessible externally. Curiously it kind of partially works, but not reliably. I can briefly connect to one of the other addresses (say xx.92), but then connectivity is lost to the others.Someone suggested I try using the Dual-WAN feature to get at least two addresses assigned to the rv082. Seemed like a good idea in theory, i.e. because the 2 WAN ports have different MAC addresses, the 2wire should see two different devices and allow me effectively to assign two public IPs to the rv082, e.g. 66.77.88.91 to WAN1 and 66.77.88.92 to WAN2. Of course failover mode won't work here, because only one is connected at a time. However the load-balancing mode did seem like it may work, but something is going on that I don't understand. Internal connectivity is working fine and I can access the internet, but for some reason the 2wire is getting really confused and constantly re-assigning IP addresses to the rv082. I don't know if this is because the host name is the same for both WAN1 and WAN2 ports, or there is something in how the rv082 does the load balancing.
 
- Is there any tricks to getting the Dual-WAN to work in the way needed to essentially have two simultaneous internet connections?

- Would it be possible to buy a 2nd rv082 and have it on the same LAN? How would I configure this?

- Is there an alternative Cisco router that may work better with what I'm trying to do?
