Some of my own additions:
1. Don't draft when overtaking a rider who started before you, it's against the rules.
2. If you don't have aerobars, stay in the drops. Knees and elbows both tucked in, chin on the stem. Keep your head down and look at the road by shifting your eyes upwards (``looking past your brow''). Don't look straight down; your helmet isn't very aerodynamic when the flat part is aimed directly at the oncoming wind.
3. Know your lactate threshold and use that information (the feel, heart rate, etc) to help build your splits.
It'd also be nice to see some more additions on how to shave seconds from those who are already well experienced in the fine art of time trialing. Perhaps some suggestions on training that focuses on threshold work or more ways to upgrade a rig to make it more aerodynamic, citing specific examples.
