Well after reading that a few times I think I follow..... PUNCTUATE!!!!
Ok, I feel better now.

Did the old tiles come off clean? No damage to plasterboard?

I'd recommend tanking around your bath/shower for sure. However, this is less of an issue with large tiles.
As for priming.... what do the instructons on the adhesive say?

Weight? Is your plasterboard skimmed? If so, you're looking about 20kg/m² max. Go and weigh a square metre of your tiles and see what it comes to. Then add a few kg for the adhesive.
