Overboarding a lath ceiling with plasterboard

hi am thinking of overboarding a lath ceiling with plasterboard. I want to batten out the ceiling first with 2 x 1 roofing battens in joist and then plasterboard to the battens. How much ceiling height will I lose if I use 12.5mm plasterboard? I'm not sure which side the battens should be screwed into (2" side or 1" side) the joist? Also what length screws would I need to screw battens through lath & plaste into joist? What length screws do I need for screwing plasterboard into batten? Additional Also how many battens would you need for a 2 x 2 metre ceiling and how far would you space them out? Would you screw the first one approx 1" away from the wall? How far apart would you space the screws? If am then screwing the plaster board to batten how would you ensure you don't screw into existing screw in batten. Would you mark this out on the wall perhaps so you have approx idea where the screws are on batten.
