code says you have to use PT plates on concrete. concrete has no adverse effect on wood. if your basement is dry, don't bother it's a total waste.
Without framing the walls all the way up they will not be bearing against the top joists
That top part provides a lot of support when someone leans against the wall
PT is required by code based on years of experience with building
Water vapor comes thru concrete...even in a dry basement
Not doing it to code & spending the few extra $'s is just stupid
I'd use the PT bottom plate, & a double top plate with 1/2" plywood sandwiched in between
That gets you to 8' 5" which you say you need
Double top & bottom = 8' 6" which is 1/2" too much
Walls should be out 1-2" from the concrete wall, studs should not be against the wall
Best way seems to be rigid insulation against the wall, then stud wall w/insulation
My additon walls are 8' 4.5" tall, the bottom 4.5" will be partly covered by the flooring & rest covered by baseboard
