1. He is not the type to freak out but suddenly waking up to be a human would certainly through him for a loop. After making sure he wasn't dreaming he would set out to first to test the limits of his new body and get acclimated to it (he would not want to be caught unaware with no idea how to move in his new shape) and then set out to figure WTF happened to him. If he could reverse it he would and if he couldn't he would carry on with his life.
2. He would continue on as a warrior. Even if his race changed it would not change who he is and being a Karashok defines him and his life.
3. He has killed a vast number of people. He is unsure of who the first person he killed was other than it was a Tal'Vashoth rebel that he and his brothers encountered when they were deployed to Seheron.
4. He likes the Mabari which they do not have in his homeland. He also has some interest in the art specific to the region but I would not say he likes it better than what is produced back home. It is different though and therefore quite interesting to him.
5. He admires the jungle cats that make their home on Par Vollen. They are graceful and powerful animals.
