Hi Richy,
The next step is to have a look at the events page and find and event on a date/location which is good for you and get in touch with Paul Matthews the office number is on the contacts page and he will clarify anything you need to know and give you a welcome to the club! Feel free to ask him anything, his motto is the only daft question is one that isn't asked!
Most of the things you need to bring with you are under one of the sections in the 'about' section of the website.
As to age restictions-
No person under 16 years of age will be allowed to attend an event unless they are accompanied by their parent or guardian. People under 16 years of age are not permitted to participate in any form of LRP combat.
Individuals between 16 and 18 years of age are required to submit a Waiver form, signed by their parent or guardian, prior to attending any event.
As to your GF coming along, but not wanting to participate in fights, in my experence that is not generally a problem, but best to check with Paul.
The other thing is just keep an eye on the forums and if there are any other bits and bobs you want to know, just post away, we are a freindly bunch!
Cheers
Alex
