You have to get out your sheers. After you have done that, you must appproach a sheep. Then PRESS AND HOLD on the sheep and it will create two blocks of wool. The sheep will regrow it's wool after a short time wgen it eats grass.

First, you have to find sheep with wool. Then, use your dyes to dye its wool to a certain color. Then, kill it or shave it to get the wool.
Yes, you can; however the color of the wool that you use to make the bed will not affect the bed's color. It will always have red sheets. The only way to change the bed's color is with a texture mod, but that will change ALL beds' colors.
No, you need wool.
No, they do not.

You can use wool for making beds and paintings. I'm not sure about the painting but I know you can make a bed in Minecraft PE
you can make beds and colored wool if you find other things
You have to put a cactus in a furnace and then apply the resulting dye to the wool.
Kill a sheep or get some sheers
For colouring wool blocks.
there is no "carpet" item/block in minecraft, but people use different colored wool as carpet for minecraft.
