How do I stop '03 XT Disc brake rub?

My first set of hydraulic disc brakes and I've noticed a slight rub. Not that big a problem but I've been unable to find any how-to online that will teach me to adjust these brakes.

Anyone seen a useful guide or can provide help here?

By looking at the brakes and manuals I've found four things that can be adjusted:
1. cable length - there are screw adjustments at both ends of the cable, I'm guessing this would be the same as adjusting the length of a brake cable but I've found a number of vague references that suggest that lengthening the cable will not back the pads off the rotor
2. caliper position - loosen bolts, apply brakes, tighten bolts
3. shims in the brake pads - haven't figured out how or if this is applicable for these brakes
4. bleeding hydraulic lines - brakes do not feel squishy so I doubt this is the problem.

What I was hoping to find is a spring adjustment to back the pads off of the rotor. thanks for reading
