i use a T55 torx socket on them big allen bolts, then use my large wratchet and bar and they undo, the caliper will then slide off the disc,

to remove the disc its just a grub screw on the face of the disc, but you may have to give the disc face a few hits with a mallet to loosen it

it's amazing how tight then can get even though the torque to do them up is small. You'll have to use a socket on them though, if you use one of those allen keys with the handle on you'll find it difficult. If you hit the allen key with a hammer, most of the hammers energy gets absorbed by the steering/suspension components

Clean up the hubs so the new disks will sit flat. Clean out the caliper and pad carriers as much as you can too, especially where the pads slide. And copper grease where anything moves really

I have just swapped the calipers and discs on my car. I had to go out and buy a 7mm allen socket as I only had 6mm and 8mm.
Halfords is about the only place that has any tools in stock to me locally and I bought a 3/8 drive allen socket to use with a smallish breaker bar I have. Halfords also sell a special 7mm allen key just to do brake sliders but they don't look all that strong. Both of them are around £4 to buy.

Do you have to bleed the brakes before you move the caliper from disc? (i will go and get my coat)
When fitting new pads some people open the bleed nipple when pushing the caliper piston back. It stops the old fluid being pushed back up towards the master cylinder, if thats what you mean.

Mine were a 10mm aswel, what i done though, was grinded the allen key down and fitted a 3/8's 10mm socket on their to get my 3/8's breaker bar on the socket and used my breaker bar to crack them off. As for the rear's iirc theres a grub screw holding the drums on (thats if you've got drum set up rather than disk), not a hub nut that attaches to the spline (had mine off the other week to sort out my rears). Hope you get it all sorted out mate!
