Hi, cwillyrun,
I apologize for being late with this post. I mentioned a few days ago that I would get you the part numbers for the Bilsteins, and it slipped my mind until now. You are correct, both front and rear are "B46". I installed B46-1739-H1's on the rear, and B46-1738 H1's on the front. I believe that the H1's are stiffer than the H2's, and the H1's are still slightly softer than stock, so, if you want to get as close to a stock ride as you can, I would recommend the H1's on both ends.
