At the Fundies level, all that will be required of your drysuit is that it fits properly and permits you the mobility to reach your valves. It is desirable to get in and out of it yourself, and the DIR recommendation is for a laminate suit because they dry quickly and you can adapt the undergarment to a wide variety of water temperatures. The tiny details like which zipper placement/entry the suit uses may be pertinent to WKPP divers, but not to the vast majority of the rest of us.
Similarly, as long as your weight and trim permits you to carry weight in the right position to allow for horizontal trim, I don't believe anything will be said about it. In general, as you go on, it's desirable to move as much weight as feasible onto your rig, where it cannot be lost. But I wear a weight belt, and my husband uses a Weight & Trim, and nothing has ever been said to him about it.
Really, the best thing to do is identify the instructor with whom you will take Fundies, and run these equipment questions by him.
