You are not held to your specific itinerary. Just write your current plan, and if that changes, so be it.

You can just put your most likely destination(s). They may also ask for flight reservations but the agency I used said outright book, print, cancel, which is what I did.
As a foreigner, the hotel will register you with the local authorities automatically so the address on the visa application really is a formality. And if you're applying for a multiple-entry visa, it's a complete non-issue.
Enjoy!
