I own 2 Showers Pass rain jackets (Eilte 2.1 and Elite Pro). 2.1 is slightly more waterproof and both have zippered vents and breathable material. Also have a waterproof helmet cover. As breathable as they are, you will still sweat unless it is cool enough outside so one way or the other you will get wet. The Gortex Active line of waterproof jackets are also good.

On the bike I will have a head and taillight and often add helmet lights. Found the NiteRider Solas or Sentinel, Hotshot or Bontrager Flare R to be great lights and will often but 2 on the bike for added visibility - one on the seat post the other on the jacket or seat bag. I would put one on the helmet but haven't found one that is rather bright with a helmet attachment method yet.
