I am a big fan of subcompact cranks. Especially on a do it all bike. A 46 x 30 with an 11-32 or 11-34 cassette is a really good range for climbs with some luggage but also for some roadie business.
Re Panniers: Yeah I think it's weird to ride with a single pannier. I think there are some laptop specific ones? I never really liked the idea of my laptop in a pannier though. So when I am commuting I tend to have a tiny backpack with just my laptop and everything else goes in panniers or Carradice style bags.
