For all Itachi knew, Obito had one eye. Whether he killed Obito or Obito goes blind from Izanagi, Itachi incapacitates him.

He screamed because it hurt, but Kamui is a dimensional ability. He absorbed the flames before much damage was done, but heat from fire still hurts. Also, Amaterasu burns quite slowly so warping it in a panic would probably warp it before too much damage was done.

Whatever's attached to him doesn't go into the next dimension. He can choose whatever he's touching to warp. Same reason he can warp people to Kamui without warping bits of himself there too. The fire was touching him so he warped it off him.
