Internet providor change

Hello all:

    I have a Cisco Pix 506E Firewall setup and is working fine currently.  We have outgrown our DSL connection and have had a T1 installed.  I'm kinda new to this network stuff but I know I can't just unplug it from my DSL modem and plug it into the T1 Router.  In the process of changing over we had only 1 external ip before now I have a block of them  I would like to change the NAT around a little. I have the following services:

FTP
Terminal Services
and normal Internet traffic (web)
and in the future I would like to bring our web site internal instead of being hosted on the net.

I think the NAT just looks at port trafic and sends it to what ever server IP the function is served on.
example FTP:  inbound traffic on port 21 is sent to my ftp server's ip address etc.

I just thought of this.  My new T1 has a Cisco 1700 Series router after the D-mark wouldn't this need to be configured as well?  

I still want every thing to go through the firewall but I would like to have severel different outside Ip's

current static outside IP
000.000.000.001  port 21 nats to 000.000.111.100  - Ftp Server
000.000.000.001  port (Term. services port number can't remember what it is) nats to 000.000.111.101 - Terminal server

I would like to have somehting like
new static outside Ip's
100.000.000.050 port#21 nats to 000.000.111.100 - FTP Server
100.000.000.051 Terminal services port# nats to 000.000.111.101 - Terminal Server
100.000.000.052 WebSite traffice Port# nats to 000.000.111.102 - Web Server

Like I said I'm new to this so any help would be nice and please excuse my ignorance if my thoughts do not match reality.

If the 1700 is being provided by the ISP, then you have a 'managed' circuit.
You won't be able to get access to it.

You'll have to re-configure your WAN port for the new IP address.
I'm not completely sure if the 506E supports multiple WAN IPs.
