I did part of the route a few years ago on the way to Copenhagen, the bit between Groningen and Bremen.
In Groningen we stopped at a hostel near the town centre though we had to chain the bikes up outside (http://www.budgetthostels.nl) the night after We stopped of at a small town called Westerstede and stayed at a place called hotel Busch, which I'd recommend. (http://www.hotelbusch.de) I remember them being pretty bike friendly. Can't remember where we stayed in Bremen but it was pretty close to the old town and I'd recommend looking up a place called restaurant flett for some good hearty German food to help with your carb loading.
Route wise, I seem to remember being on bike paths the whole time. There is pretty comprehensive maps of bike routes in both Germany and holland, though can't seem to find the link now.
