1) I think you are describing the raw jeans. There are two varieties, made in Japan (MIJ) and made in Italy (MII). They have different prices and are slightly different.
In addition, there have been various pairs of jeans over the years that look more or less like raw jeans, but aren't actually raw. Infinite Mind from FW 09 and the Monk jeans with the zipper on the back pocket from FW 10 are two like this that come to mind, although both of these have a little bit of whiskering at the top of the thigh. If you were to look at either of these side-by-side with the raws, it would be obvious which is which, but if you just saw someone wearing them, it might not be immediately obvious.
2) I have both the indigo and black raw denim. They both bleed. For example, if you wear a pair of white high tops and if the bottom of the jeans kind of sits inside the ankle, it is very common for the tongue and/or the inside of the ankle to get stained. Also, I have a white belt that has some blue on the inside from wearing it with the indigo raws.
Eventually the raw denim will stop bleeding, but I've had my pairs for quite a while and they both still bleed. I don't wear white shirts or white shoes with them.
I don't know how to avoid bleeding. Maybe someone else here can help with that, and I'd be interested to know as well.
