I'm building my new home and using hydronic radiant heating embedded in gypcrete (maybe lightweight concrete). I got Dan from Blueridge to design everything as well they built my manifold for me (looks good). Now I have an idea of what I need to do but I don't want to miss something and figure it out after the pour, is there any good websites or books available on this?

 I figure I'll give the house a good cleaning, lay out a grid with chalklines, box out all registers etc., then I guess I just start laying the tube??? I can usually figure stuff out but this kind of scares me.
