I have suggested to put the VPLS link in area 0 to have more flexibility.
I would put the Germany office internal subnets in a separate area.
I would put the HQ office infrastructure in area 0 and HQ client subnets in a different area.
How much to extend area 0 in HQ is your choice. However, using multiple areas in OSPF provide some benefits like route control on internal routes.(you can perform route filtering at area border if needed and route summarization).
Using multiple areas is not only done for scalability, but also for better control.
Avoid to use redistribute connected and use network ... area + passive interface instead to avoid unnecessary external routes (that cannot be filtered at area border).
