Dear Miro,
Welcome to NGO. The new airport is much nicer than the old one, and while not as big as NRT, I like it much better. There is a nice open airy feeling to the terminal and because it is quite small all the shops are located together.
You will have no problem finding plum wine at the shops as duty free alcohol is a very big seller at the airport. You can also stop in for a nice bowl of noodles or other Japanese dishes while you are waiting.
Also for the NGO-MNL leg, the flight should open up a bit so your last few hours should give you a bit more space to spread out.
Enjoy the trip and feel free to drop me a line if you have any questions about NGO, as I pretty much live there recently.
