Okay, here is how it is now.

1. I have a backup taken using backup menu, as well as the stock backup tool But can I use those to restore contacts and calendar stuffs to other phones? Ovi will help?

2. For me, both E7 & Lumia 800 looks dumb phone. Lumia 900 is out of the price tag compared to N900, so they wouldn't obviously give me that. And 820/920 all are just in 'Coming soon' status. Pureview, again not in the same price tag.
3. They have been trying since 4th oct and couldn't fix my usb hub back onto the board. Also, they tried to swap the board with an Old n900 board, whose IMEI found to be from England and is more than 2 years old already. I didn't want such an unprofessional replacement. So turned it down and escalated the problem. Asked for a new N900. But they don't find one in India they say.
