Those points are earned. It is not like the cash shop. But if you can leave your computer over night you can get up to 200 tokens if the 4 token per 15 minutes is still up. Anyways yea u need to be patient with it. i got 2500 of those for 5 nights like 5 more and I'm good.
From what I know, you'll need a full account, in order to buy Cash and so forth, so anything related to that, includin "netstore" (I believe) won't help too much, I'm sorry mate. As for the Dogi, just like the user above said, staying online will give you some sort of points, you can visualize how many points you've gathered by pressing that yellow T on the blue circle-background icon, in game. Once you gather 3500 points you could just take it from there (it's on the third Tab if I remember well) :) You just have to give it a bit of time unfortunately but.. that's the best you can do I guess.
