In terms of assigning "weights" to various assignment types in my classes, the course syllabus spells out minimum and maximum limits within categories, but I do have a measure of flexibility. I tend to come down on the side believing that as my students get out into the "real world," they will be evaluated more on what they do on a daily basis, day-in and day-out, than they will on one particular day. Therefore, I like to assign as much weight as I can to class participation and homework assignments. As for sharing grades, the module recommends a couple of online gradebooks, but I use Engrade. It is very user-friendly, and the students can log in at any time to view their grade in the class. It will show them not only their "averages," but also their marks on each particular assignment within each category.
