a book i would recommend nevpugh, is Robert Fenner's "Conscientious Marine Aquarist". Most fishkeepers consider it to be the "bible" in marine fishkeeping.
as in most cases in this hobby, you will get about 15 different opinons on one thing, but as for seeding a tank with live rock, most people add it all at the same time. and the bacteria from the live rock will spread to the tufa rock, but dont expect the tufa rock to have a bunch of coralline algae on it (it won't look "live").
as for cycle - throw in about 2-3 raw cocktail shrimp from the grocery store. then wait for your readings, ammonia mainly, to be at 0.
