Don't sweat the #2 diesel thing. It won't hurt your engine if you get #1 or blend of the two. #2 has a higher energy content and is usually a bit cheaper, so it is preferred in warmer weather, but it contains paraffin so it gels in cool weather (around 18°F). #1 is almost paraffin-free, so it has a much lower gel temperature (around -40°F). Most stations will carry a blend that is suitable for the local seasonal conditions. It's not usually an issue except for truckers who filled up in a southern state or those that bought diesel in bulk during the warmer months. There are additives, but usually they can only lower the gel point 10 or 12° as they don't get rid of the paraffin, just lower the temperature at which it can gel.
CC/CD SAE oil specifications are obsolete and no longer available. Current standard are CH-4 and CI-4, either of which is a suitable substitute. Basically, if it is sold as a Diesel engine oil then it should be fine in your tractor; you only have to worry about it if you are contemplating a stash of 20 year old bottles you found in the back of the barn.
