im doing a shower in the basement i am breaking up the floor and pouring new concrete there.how and what type of membrane should i use.I am assuming it goes on top of the concrete and up in between the studs and the concrete board. but then will tile stick to that on the floor? and how high up on the wall should it go?

I want to assume you're breaking up the existing floor for drainage?
I'm also not certain al all why you think you need a membrane. Once you have your Drain plumbing set in the new concrete, just use an appropriate shower pan.
Ah ok , DUH...You want a vapor barrier to the exterior of the shower. Certainly you CAN do that, but you wouldn't find it in home construction in the upper levels of a house. Hopefully the basement is sealed externally, preventing seepage in the walls. I'd probably use construction grade foam sheet 2 or 3 inches thick between the studs; wall the shower with concrete backer board, seal the seams and screw holes, and install tile.
No offense but a shower pan would be as suitable as tiling the shower floor, especially in a basement shower. If you choose a concrete floor sloped to the drain, certainly tile will adhere to it with an exterior, or poly based mortar, just as in showers on any level of any house.
You may get other opinions, but I tile all the way to the ceiling.

NO, the membrane should be beneath the concrete, but lay it on something soft such as building sand. this will stop any hardcore from piercing the membrane when you pour your concrete. as it's in a basement you may have to tank the walls as well. check with building control.
1000 gauge polythene is adequate. check with building control they may also insist on 100mm insulation under the concrete also...

up the wall at least 6 in ,on the floor use floor mix available at most tile shops, mix it just wet enough so it holds together when u squeeze it ,tamp it into place with a wood float be sure to slope it toward the drain

Check your local building centre. They sell shower kits that contain everything you need. Teh kits come with a foam base that will help you ensure the shower floor drains properly and a foam berm to prevent water from escaping.
