Is there any substantial difference between the 2 except for the 3d matrix Fill Flash with the "D"?
Are the optics and build the same? I'm not planning on using a the 24mm w/a flash so am I ok going with the non-D?

This is a popular misconception. The "D"istance information provided by the "D" chip in the lens is used by lens and camera in 3D matrix metering, not just flash metering.

Exactly. What happens is that sometime Nikonians mention they do have non-D lenses and have never notice any difference.
Well, there is if you do have a N70, N80, F100 or F5. Otherwise, yes, you will not see any difference. The other reason this is not a well known fact is that there are no comparison shots being made and posted on the WWW (that I know) with one and the other to make a substantiated case of it.
Furthermore, we want to continue being polite.

What Ed and jrp have said is very true, so it's something you need to take into consideration. I would only add, so that there's no confusion, that it's only the "3D" that is absent from the metering -- the camera will still provide matrix metering. Basically, 3D matrix metering is divided into four steps: 1. Brightness data from each of the segments is read and analyzed; 2. contrast of each segment is compared with the others; 3. distance information is calculated; and 4.defocus data from the AF system is added to the equation. When you use a non-D lens, the camera simply leaves out the third step. Now how much that might affect the final product (your photo) is hard to say and may vary depending on the situation. Obviously, there were great photos taken before 3D metering, but on the other hand that's one of the most attractive features of the newest Nikons. Anyway, I hope this has been of some help. Take care!
