TACX bar-end lights are great. They shine a white light forward, a red light rearward, and even have an amber flashing turn signal (which I never use). Not powerful enough to illuminate the road, but certainly attention-getting.
For the main headlight, I like the $25 Cree XML T6 lights on Amazon. They are a knockoff of a >$100 light, and they work great, either on the bike or on the helmet. At $25, you can run as many as you want.
Knog V4 taillight for the seatpost. Very bright, lots of flash patterns.
If your cleats are SPD, you can get pedals that combine a cage with the binding, so you can either cleated or regular shoes. I commute with clipless, if you are used to that on your road bike you will probably want at least the option of clicking in on the commuter.
Fenders, as full coverage as possible, with mudflaps. I think the hammered alloy VO fenders would look classy on that bike. Edit - I didn't catch that you put 25mm tires on. In that case I recommend the PDW Full Metal Fender, which is a strong but sleek, alloy fender, won't rattle or shift, looks nice with narrow road bike tires.
