As long as everything's got a big blue "H" on it, you'll be fine!!
On a more useful note, can you get anywhere that hires kit out? Dive as many diferent bits and pieces as you can and see what you like best. Be honest about where you see your diving going so that you don't get stuff that you'll be looking to replace in a years' time. You may find that the bug bites and you end up doing a lot more than you're planning on.

Gas strategy? For really smelly ones, eat sprouts.
