I always recommend the Topeak MTX system of racks and trunk bags, because they are relatively inexpensive and readily available and because they are SO COOL. I'm a big fan of not using backpacks or messemger bags and getting the load off you YOU, and onto the bike. So a trunk bag for your change of clothes/lunch/work stuff & a pannier for the laptop would be a very nice setup, IMO.
