First of all, that is borderline heresey, claiming the developers messed up the story. It works because they stay away from setting many definitive answers allowing the player to explore and build their own ideas and theories. But I'm not here to argue that. Your first question is "why would the Chosen Undead go and kill all of the 4 creatures to fill the Lordvessel without even knowing how to do that in the first place". The story is linear, you're not even aware that you are going to collect the souls until after you gain the means to do so. You aren't just told the end game goal and thrown into Lordran without any clue as to what to do.

And Solaire obviously isn't following you because you have to summon him into your world, meaning that 1) he is in his own world, not yours, and 2) that he had to get to the Kiln before you so that he could place the summon sign in the first place.

As for how Solaire knew where the Kiln is, plenty of people already know several secrets of Lordran. That Solaire is able to find the Kiln isn't that shocking. Or, if he WAS the firstborn, then he would know exactly how to get there. Or maybe he just knows because his covenant is so entwined in the worship of the gods. It's obvious that he knows more about Lordran than shown, as he's able to navigate it with relative ease and is fully aware of the existence of multiple worlds and times. Hell, he introduces the player to the concept.
