I'm thinking about getting a PS4. I have questions.

[Intrinsic]

1. Most likely. If the destiny bundle sells very well then there will most likely be a white PS4 standalone sometime next year.
2. Well, if a game uses online multiplayer, then it will not be able to be played without PS+. This part is funny though, cause you really only need PS+ for online multiplayer and not to get your games online if that makes sense. However, you should consoder PS+ even if not for the multiplayer. It pretty much pays for itself. Not only do you get discounts on games, you also get free games every month. 
3. Only things that comes to mind, Kingdom come (2015), the witcher 3 (2015), Alien isolation (2015), the witness (2015, this is no mans sky kinda indie if that makes any sense), Rime (2015, again no mans sky kinda indie)..... yup thats it.

Hope that answers your questions, if I may add though.... you really don't seem to not only not like the PS but you seem to be against everything that a PS type console stands for. Having said that, I think you spending all that money for something you obviously don't like is pointless; though its your money so ignore me :) . Especially if you are only doing it for a white console lol. What you have done in your post would be the equivalent of saying I want to buy  wiiU but I need ppl to recommend multiplayer only games and I don't want any nintendo first party games lol.
