If you just want to add a bit of bling, go for the EighthInch cranks. No shame in wanting something shiny, as long as you understand that they're not going to be the stiffest cranks out there. They work well for me, but I'm a spinner, not a masher.
For pedals, that depends on whether you ride single speed or fixed. Even though I have flip-flop hubs, both my bikes are set up as single speeds right now. So one has grippy flats, the other has some nice sealed Wellgo pedals set up for clips and straps.
I've heard nothing but good things about
Wabi clips and straps, but you may not want to drop the cash for their Exustar pedals. (Note, I have a Wabi Classic, and I'm very partial to the brand)
