You posted a few questions in the shiny thread, I'm not sure if they've been answered yet so I thought I'd give it a shot.
1)You have to select a starter to see if it's shiny. As far as I know the poocheyna is shiny locked so no worries about that. (that wasn't part of your question but i thought i'd mention it! :3)
2) I think the assumption right now is that the odds are the same as XY so 1/4096. I haven't seen any evidence otherwise. There are some methods in the game that people think might reduce the odds (dexnav searching which is similar to changing, and people are curious about the odds for the Mirage spots where you encounter various legendaries but still no actual proof for the latter method for reduced odds)
Edit: I've also seen people use the dexnav to sr. So that's an option if you like to do so. You basically just encounter and then soft-reset. So like sr-ing but with a wider range of pretty much any target.
3)Yep, still the same.
4)Dexnav is the only new method I think. It's very similar to chaining and you get it soon after you get your starter. It can be also useful for finding unique pokemon moves and pokemon with better stats.I think if you search around there are a few guides for it, I'm not sure how it works aside from the fact that you encounter a lot of pokemon in order to get your 'search level' for that pokemon up .I don't know if the odds for it are lower/higher/the same for chaining but it seems like it takes longer than traditional chaining does.
