Questions on white collar

So after finally finding a seemingly reliable white collar boxing organization, I signed up. I now have some questions.. Am I expected to bring my own gloves with me? What should I bring on my first day? How do weight classes and cutting work? I weighed myself this morning and I'm 206 lbs. I'm wanting to fight at cruserweight over heavyweight, would I need to be dead on 200 lbs for them to put me in it? Or would they be like okay we'll help you cut those extra 6 lbs on fight week? I don't want to be chucked into heavyweight because I'm a few lbs over CW. What can I do to get my fitness up and do for myself? As of today I'm going to constantly practice on my shadow boxing for accuracy, faster punches and to get my stamina up so I'm not breathless on fight night. I already run almost every day for fiveish miles, I try to do 200+ push ups and sit ups a day and I go fitness swimming every 3-4 days where I aim to do 100+ lengths. Do I seem reasonably fit enough to not be seen as a joke? What else can I do to make sure I get that win? Any advice I would really appreciate, I'm obviously a beginner but I want to give myself the best chance to put on a dominant performance and get that win. Thanks :)
