NCA
Dont listen to rumours about who the RAF are accepting for NCA because the answer in reality is nobody, at least until the Defence Review in October. Whichever fleets get binned, there are going to be a lot of spare WSOps about ripe for re-training, which reduces the need to recruit new ones.
What you will need for NCA right now is a lot of patience. There are few (no?) RAF vacancies at present, so I would recommend applying to all 3 services whilst improving your quals or getting a real job.
Good Luck
