So far I am having a blast with this camera! I am starting to feel the urge of buying a faster glass, but I will explore the capabilities of my Rokkor 40mm before spending more money on glass.
Before you try faster, I'd suggest going wider -- get a 28mm or 25mm lens.
The 40/2 M-Rokkor is a fantastic lens, and was my first on the R-D1 as well. I've since bought a silly number of other lenses, but I'm not sure I've yet bested the 40/2. Also, f/2 is usually fast enough, particularly outdoors; and indoors, the ISO 1600 performance of the R-D1 is great, especially in B&W.
