There is only one translation of the Yad. It’s the Chabad Moznayim one and I have some issues with it, though overall it is a good translation.
The Kitzur Shulchan Aruch represents the backbone of much of Jewish Law as practiced in the past century. I would advise starting there so you know what to do and then branching out into other things after. It is not a shortened version of the Shulchan Aruch. It is its own Sefer and stands entirely on its own merit and that of its author.
