PIX 501 switchover from t-1 to cable modem need help asap

Here is my dilehma, I am new to pix config but can do access-lists, etc and some config changes, the problem is I don't know how to do a switchover from our t-1 provider to the new cable modem with higher bandwidth.

my old IP was 209.58.252.x

my new IP is going to be 24.234.163.x

here is a sample of my config. Any help would be greatly appreciated!.....
