This is it! Take the intros seriously and use them as a real guidepost for understanding the work in its totality. This is often read in selections that are used to support some preconceived notion of what Kant is doing. Just look for him to do what he says, the many seeming inconsistencies will start to work themselves out with the work as a whole.

This is a great early lecture. One can gain a good overview of the Kant as well as a basic picture of the ways in which Marty works. Heidegger many times uses interpretation to move his own philosophy (why not), but here he is closest to the text.

This, unfortunately out-of-print, book is the ultimate treatment of metaphysics as approached by Kant. This work covers all of the essential moves of a Kantian approach to objects as they relate to the human subject. The object, in the Critique and laid out here, is found in between the thing and the human identifying it as object. Make it to the second half.

This is the starting point to understand what Heidegger sees as the essentials of the human condition and how it is that we are to proceed forward in understanding our place in the world and the questions that are essential to our condition. See below for an excellent reading companion to this sometimes verbally obtuse work.
