Welocome to SCUBA BOARD.
I would just buy the BASICS (SNORKLE , FINS , MASK) You cuold buy a good set up of 1st stage ,second stage and octo The rest you can get after you get some dive . And you figure out what you want and how you will be diving ,and where . all these things will change what you need and what you like . If you will be a vacation diver will dictate how much you dive . If you only dive on vacation 1 or 2 a year it may not be wirth your money to buy . it can be expensive and a pain to take all your gear with you . If you will do a lot of diving localy this will show you that you may need a good cold water wet suite . and will be wirth you time and money . I would dive for a while and find what you like and fitts your stile of diving and needs
good luck
