You should be fine w/ the connection in Tokyo; however, I suggest you request the seat closer to the door when you check-in in BKK.
Once you clear security in Tokyo, quickly proceed to your Portland gate.
Yes, you may put down the hotel. Must have the name, address, & phone number of it though.
I have flown NWA for over 10 years. Only once did I have problem w/ my suitcase and I was totally my fault.
Usually the flight gets in a little bit earlier than schedule, so I don't think you'll have that much problems. Your bags will be check-thru to Portland.
