I just bought my first Rolleicord today and so I might not be the best guy to tell you how to load film.
To answer 1: you seem to have a Rolleicort I (type 1)
2: They were built between 1933 and 1936. You can tell it is a pre war model by the acronyms DRP and DRGM. This stands for Deutsches Reichs Patent (German Reich Patent) and Deutsches Reichs Geschmacks Muster (basicly a copyright for the name). In post WW2 models you will find DBP and DBGM. They switched from Reich to Bund (German Federal Patent).
3: I won't dare to tell but I am sure by now you have figured out how to load film.
4: The camera I bought today is a Rolleicord V (1954-1957) and I have to line up the line on the back of the film with two red dots to the left and right of the body.
Hope this helps, I've got to go and take some photos!!!
