I have some dumb questions on deadlift form. I have been wanting to try the barbells for some time but have hesitated a bit because I'm concerned about injury. So basically I have been doing the machines and hand weights (up to 30lb). But yesterday I thought I would take a baby step by trying out with just the bar and see if I could manipulate just that a little without killing myself or falling over the equipment. So I took the bar from the press rack, which seemed the easiest to get at; all our barbells here are hung up in different cages and racks. First I had to get the weights off the bar, which required some experimenting to figure out how to undo the clamps (I am not very mechanically minded) so I was relatively proud when I accomplished that. Then I put the bar by itself on the floor and tried to do the form for a deadlift, since that seemed the least complicated balance-wise. I have studied the stumptuous articles and a few other pictures for a while, but hadn't looked at them recently.
Well, my form must have been pretty awful, because a gentleman (I think he's one of the rugby coaches) actually got off the exercise bicycle to come and correct me, very nicely. And when I got home I practiced some more with the broom and also my hand weights, because the stance feels kind of awkward to me, and I have a lot of trouble keeping my shoulders from rounding down (especially since without any weights on it the bar is pretty much at floor level).
I tried to find some action shots online and realized that most of them actually show a different stance to Krista at Stumptuous. She shows more of a squatting or crouching stance, with a low pelvis and pretty upright back, compared to say, this guy at stronglifts who has higher hips and has back inclined more forward. Stronglifts guy also says specifically that the deadlift is not like a squat. I think that's what coach guy was trying to tell me to do.
When I tried the higher hip stance it is a bit easier to keep my back straight and feels a bit less awkward: when I do the Krista crouch I don't quite know how to get the bar past my knees for one thing, because they are sticking out in the way as I go up. (Maybe I have a shorter torso than she does?) But I don't know if the more bent-over form is something that will be horrible for my lower back.
Any tips or suggestions on what to do here?
ETA: Also, hands inside or outside knees? Most of the directions say feet should be "shoulder width apart", but also your hands are supposed to be "shoulder width apart". They don't show where to put your hands though.

The issue with deads, as you know, is that they work legs and back. Put 'em on leg day after squats, and fatigued legs may mean more stress on the back during the deads. Put em before squats, and fatigued legs may mean more stress on the back in squats. Put 'em on back day, and you're working legs on back day, which may not be ideal because it eats into recovery/growth time from leg day. It's a conundrum, wrapped in an enigma. OK, maybe not.
