Do not adjust the bar because you think your hips are too high. The bar needs to be over the middle of the foot, counting the part of the foot under and behind your calf (so middle of the foot does NOT only mean the part of the foot you can see when looking down). Hence, as Rippetoe states, it needs to be an inch from your shins at the start of your lift, when you're standing straight up. Bend your legs so the shins come in contact with the bar without lowering your hips or moving the bar, push your chest up hard so your back is flexed, fill belly with air, and pull.
Your back angle, if the bar is set right, is completely dependent on your individual limb lengths, like you stated. But you shouldn't compensate simply because you feel the need to "look" like other deadlifters. If you do that, the bar will shift away from under your scapula and you will compensate by pulling it back under your scapula during the lift at the compromise of an inefficient and thus weaker pull, and/or lower back rounding. That's why you see people's hips shoot up before the bar comes off the ground when they've set up wrong. The bar will NOT come off the ground until it's under your scapula, unless of course you're pulling a relatively light weight.
If you're feeling inhibited when you pull, or your shoulders are bellow your hips, you either need to fix your deadlift start position or you should do some mobility work. Really tight hamstrings can wreck a deadlift.
