You can go Back to German rom, if you want. It should be a file on your cd. Additionally you can download it from here:

For OZ 16 MB should be enough. I flashed mine with an old 16 MB Kodak Card once.
For Sharprom I guess you will need 32 MB. But I am not sure about that, because I dont deal with Sharprom anymore.
Openzaurus supports German Keymap. Depending on the OZ Version it is more or less tricky:

The handwriting is ok. I never Compared it with the Sharpthing, cause Sharprom is always the first thing I remove from the Z.
There is also a very active and nice German Community online:
