Brad has it exactly right. Especially the part about reading EVERYTHING on the chart. Almost everytime there are two pages to the chart itself, the first page being the actual diagram of the route, and the next page being the route discription, which spells out for you, in words, how ATC will be expecting you to fly the route. One of my biggest pet peeves is seeing pilots file a departure that clearly states that the pilot has responsibilities to take care of after departure, and they just fly runway heading off into no where. This is apparent if you fly out of PHX. Their departure procedures specifically ask the pilots to fly specific headings after departure, but 75% of the time, this is disreguarded, to the annoyance of the controller, obviously.
All in all, what I'm trying to say, is that you should read ALL the chart has to offer, not just the nice picture on the front
