1) Is it saying you might not have enough time, or that "this plan has you arriving at meals or attractions a little later than you'd prefer" (or something to that effect)? If the first, are there attractions not listed that you plan to get to? If the second, it may very well be triggered to do so by your very first step, in which you have TH for 8:00 but will arrive there at 8:09 because of the time from park entrance to restaurant. If it's just saying not enough time, then I would email the link to the admins for help because you have 2 hours left before park closes.
As to which FPP to get, it looks like your crowd level and wait times are insanely low, so I wouldn't worry too much about it. That said, it does look like your longest wait is Dinosaur so I'd grab that for sure.
As to Kali River Rapids - if you haven't been on it, you should know that you WILL get wet on this ride and a good many of you may well get soaked. The weather being so variable in January with regard to temperatures I would consider skipping this one myself. Brrr!
