May one cut tzitzit strings that are too long? I also noticed that one string is longer than the others. Is this intentional? Why?
One may cut the tzitzit if they are too long.(Shulchan aruch Orach Chaim 11). There is one string called the Shamash which is intentionally longer because it is wound around many times the other Tzitzit. Sometimes it remains long even after all the winding.
