its like your going to class. just wear neat office clothes and adhere to the grooming in the manual (I think you get your photo taken for your ASIC on first day so do nice makeup), bring stationery, a notepad and maybe a folder to put your booklets and stuff you will get. thats pretty much it. first day you dont do much just get all your manuals, orientation to the company, meet people and do a test etc. Have you got your booklet in the mail with the things to study? I dont think you will get any other sort of confirmation aside from that. Did they tell you about parking? you park in the long term carpark and get the bus over, make sure you leave atleast half hour to be safe and arrive on time, then they get you to fill out a form when your in class and when your leaving the carpark you go to the boomgate give them your ticket and the form and they let you out. (but i may be wrong, got bad memory). see you in the crew room
