The guys who have answered your post all have good advice. I'll add only a couple of pointers.
First, with your back arched, ELBOWS LOCKED ABSOLUTELY STRAIGHT, and the bar very close to your shins, you may be bent over farther than you expected. That's OK, as long as you resist the temptation to let your arched back get "rounded."
Next, everyone is tempted to give the bar a "jerk" off the floor, which involves slightly bending and then quickly straightening your elbows. Don't. You'll probably get away with doing that, with one wheel on the bar, reinforcing a bad habit. When you are lifting closer to your current limit, that technique will cause you to round your back suddenly. The bar will drift forward in a "semi-stiff-leg" deadlift form, making the lift MUCH harder. If you don't rupture a disc while that's going on, you're having a pretty good day. To avoid the temptation, concentrate on starting the lift by pushing the world away with your feet, rather than by pulling the bar off the floor.
The articles, pictures and videos of Louie Simmons, Dave Tate, and the Westside Barbell Club guys doing deadlifts may deal exclusively with "sumo-style" deadlifting (very wide stance, grip much closer than the shins). If you have RELATIVELY short torso and long legs for your height--or if you find it impossible to do your best below-parallel squats with a very wide stance--"conventional" deadlift style (roughly shoulder-width stance, grip just outside the shins) is for you. Many world record deadlifts have been done in conventional style, but it somewhat alters your training. (You can't get anywhere near your potential best conventional deadlift, by doing great squat training and a few light "speed deadlifts," as the Westside guys do.)
Given enough bananas for incentive, most competition powerlifters could teach an ape to deadlift, "in person." It's harder to do it right, through cyberspace. If you run into a powerlifter in the gym, ask him or her to critique your form. Good luck!
