If you're hunting small water like beaver dams, I'd look for about a dozen decoys, half a dozen quality mallard decoys, in poses that aren't all heads up , and a puddler pack from one of the manufacturers that package them, usually a pair of widgeon, pintails and gwt. If you're competing against a bunch of clowns with multiple spinning wing decoys, you may have to play their game, but I think you're better off w a jerk cord. A length of cord that will get to a mounting spot, and a piece of surgical tubing for the end away from you. I use trot line clips to attach the three decoys I use to this cord.
For rigging I do everything with Texas rigs, look on YouTube for instructions. If you end up with a lot of decoys (yeah it happens) snl corp is the best place I've found for bulk 400 lb mono and crimps, but for a dozen or less you can find them already made up at a cabelas or similar.
Welcome to the addiction, and remember hide your shiny white face, don't move, and learn when to call, and when not to, and most importantly, little Debbie's beats hostess every day.
