Roush New Saleen Owner with some questions :)

I just purchased a 2002 SC Saleen and I have a few questions about the car. But first here is some information about the car:

2002 supercharged with 18,000miles. 5spd.

First: Does the intercooler use water? If it does, how do I store the car in the winter and prevent the water from freezing?

Second: What rear end gear ratio does my car have?

Third: Is there oil in the blower that needs to be changed? If so, how frequently, and how can it be done?

Fourth: The previous owner removed the ID number on the front bumper cover (yes it's a real saleen I checked ) I ordered a new one from Saleen, but if anyone has a picture of that number from their saleen it would be a big help in the placement once I get mine. Thanks

fifth: Where can I find production numbers?

Here is a picture. Thanks for any help.
