Type II base for a big wood stove
You first need to know the installation clearance specs for the stove and your city code requirements. Asking here without that info isn't going to help you.
However, you need to remove the laminate in the area of the stove. The floor is a slab, so why did you think of installing concrete backer? You're already got concrete. Also, you mentioned 5 sq. ft. Did you mean to say 5 ft. sq.? That's 25 sq. ft., more like it.
As far as I know the wall needs to be "shielded" in order to reduce the stove's stated clearance minimum. A shield in made by furring out 1/2" concrete backer and leaving the required space at the bottom and at the top for airflow. Your building department will tell you what those are. You then apply a fire proof tile with thinset that comes in a bag and you're good.
