copy iCal settings

I am running OS X 10.6.8 on my new iMac. Need to copy from Mac OS X 10.4.9.

I want to copy my iCal settings from one compter to another in case the old one dies. I copied the settings from the old computer. Where do I find the iCal settings in OS X 10.6.8? I want to copy them elsewhere in case there is a problem and then I want to replace them with my settings from the other compyuter. I looked at the location below, which is where I found the others on the old compuuter. and don't see them.

/Users/YourUserName/Library/Application Support/iCal/

Thanks for your help.
