Nothing to stop you showing at all. You should write and tell the Kennel Club that she is spayed before you make any show entries.
As you have no experiencxe you really need to go to ringcraft classes, and tell the trainers that you know nothing about showing.
They will then be able to help you get the idea. I beleive that your breed are normally stacked (held in postion with your hand hoding the muzzle and other hand the tail, and you put their feet in the right places by hand). With luck ther should be some stacked breeds at the club whose owners can show you how to do it.
I would then buy one of the Canine Weeklies Dog World or Our Dogs, they can sometimes be found at large Newsagents, but most people subscribe or get their Newsagent to order it weekly. I would order both for a month and decide which one appeals to you most in editiorail content, as they will both have show results and Judges Critiques abnd shwo adverts.
She is already old enough to be shown, so I would get some entries off to some Opejn shows as soon as you start at Ringcraft if she is already a confident sort, but wait until you see how her training goes if she is not.
A list of Ringcraft training classes can be obtained from the Kennel Club, or if you say where you are board mebers may know of one near you. :D
I would also go to a couple of shows on your own first so as you can see what it is like, and with luck make some aquaintances in your breed or other HPR or Gundog exhibitors.
