ADSL, 1841 ISR Router and multiple static IPs

I have a business DSL account with Verizon and 5 static ips
(134.23.212.19-24/24). I have three device interfaces (PIX firewalls)
behind the router that each need 1 static IP associated with it. On
the inside interface of the router I have FE0/0 and FE0/1 and have
configured them as 192.168.1.0/24 and 192.168.2.0/24. We're using NAT
to have:

134.23.212.20 = 192.168.1.11
134.23.212.21 = 192.168.2.11
134.23.212.22 = 192.1682.12

We can get the IPs to map correctly using the below configuration.

Our big problem now is using Verizon. Since we're using a Cisco router
with the HWIC instead of the cheap Westel they will not support us
(understandable). However, they've been unable to provide us the
information we need to configure the HWIC. It seems we finally have
the PVC value but the reps have never heard of encapsulation. Out
account type changes depending on whom we speak with but we now know
we're not using PPPoE, so don't need a userid/password. I appreciate a
head's up from anyone who's dealt with Verizon DSL and/or business DSL
with static IP blocks.
