Reports/Modules for Geman Tax Issues

Sorry this is a bit special for German users.
We are looking for reports or modules which enables the mandatory communication to the german tax authorities. Therefor a couple of standard forms for Germany should be printed. In detail these are:

Umsatzsteuerjahreserklärung Gewerbesteererklärung Körperschaftssteuererklärung Antrag auf Dauerfristverlängerung

Does anyone know where I can get these forms/reports or is Navision not able to do this? The answer from MS through our NSC was that MS will not directly support these forms.

Additionally we are looking for an "ELSTER" module which transfers the tax claims electronically to the revenue authorithy. This electronic transfer is mandatory from January next year. Our NSC says only "Microsoft is working on it" but I can't get any release date. Does anyone know more?

I always tought Navision was made for Accounting - But I feel like we are the only one company who is working in accounting with Navision?

Thanks for any tipps, comments or suggestions.
