Yes. Sasuke kills him and 'absorbs' him, or takes the power of the white snake that was inside Orochimaru.
After many experiments, his true from is a giant white snake composed of many small snake if you check the fight between Sasuke and him where he shows his true from. So he has snake eyes.

No. Sasuke's snake is dead.
in 115 in shippuuden
giant white snakes come out of his body, he can summon that giant snake and he heals faster. thats all i know
yes, He has it by consume the rest of Orochimaru power after Sasuke kill him.
when sasuke and itachi fought itachi killed orochimaru with susanoo and sasukes curse mark left but he can still use snake style jutsu but not curse mark(he did get amaterasu,mangekyo sharingan and black crow style jutsu but he doesnt use crow style and itachi wanted sasuke to take his eyes so sasuke would get eternal mangekyo sharingan but sasuke didn't).
In manga...YES! He wasn't bad with Orochimaru because he was only fulfilling his ambition to kill his brother Itachi. After Itachi died because of over-using Mangekyou Sharingan. Sasuke decided to defeat Orochimaru. Whist with Orochimaru Sasuke formed the group Team Snake. Team Snake contained Suigetsu Hozuki, Karin, Jugo and Sasuke.Team Snake's focal mission was to kill Itachi. Now Itachi and Orochimaru are dead. Sasuke turned to Akatsuki which had Madara Uchiha. Then Sasuke decided Team Snake was now called Team Hawk. Team Hawk with Akatsuki now plan to destroy Konaha, but Sasuke only plans on killing the elders. Sasuke killed Orochimaru to save all Orochimaru's captives. At the moment Sasuke is on the bad side; but he still has a heart!
I'm not pretty sure it's never been shown how they trained . But before Orochimaru died Sasuke used his Sharingan to copy his ultimate technique where he need a Sacrifice body to stay alive called ' White Snake Reincarnated '
i used to think that it was a snake but now its most likely a hawk
