For the calipers, get a proper 12" long breaker bar and a brake caliper key (like an allan key but even lengths either side of the right angle with a cusioned grip). They will give you the best torque transfer on the various bolts and make the job so much easier.
Have a spare long M10 bolt with a couple of non locking nuts to hand. If the brake disk is stuck to the hub then place the bolt through the caliper mounting holes, put one nut on untill it reaches the hole, then put the other on the end of the bolt. Tighten the inner nut so that it pushes the other nut and end of the bolt agains the disk. The disk will release with a loud bang and no damage will be done to the wheel bearing.
