We are renovating our 1890 farmhouse and adding an extension to it. In this extension will be a new stand up shower for which we have bought some 12 x 12 marble tiles. The beginning of the project will be on a wood floor, but we just need to know the steps for making the right foundation and slope for the floor of the shower. The tiles are not the flexible smaller squares, but the 12 x 12 solid slabs. If anyone knows the correct procedure for this please educate us?

AFAIK, you still need a mud job. In other words, the slope is created with mortar. Search youtube for some videos. Are the sides of the shower going to be tiled too?

it will all be tiled, but do we need sheetrock then hardibacker? or can we use just straight hardibacker without sheetrock behind it?

Here's a tutorial on making the shower pan. You will be hard pressed using 12x12 tile on the floor since they don't bend to the contour of the slope. Using 12 x 12 sheet tiles of 2x2 tiles is better. http://floorelf.com/how-to-create-a-shower-floor-part-1

On the walls, you would insulate, of course, and apply a 6 mil vapor barrier, then conventionally use either Durock or equivalent on the walls. No sheetrock. More expensive systems (Schluter) exist and you can research them if you like.
