As a first start, might I suggest that you download and peruse at length the CAA's licensing document LASORS from
http://www.caa.co.uk/publications/pu...ls.asp?id=1191 . Currently it's the 2004 version; the 2005 version should be out soon.
Full sponsorship is virtually unheard of these days - and a full 'Integrated CPL/IR with ATPL knowledge' (commonly termed a 'frozen ATPL) will set you back around £50k with no guarantee of a job at the end of it.
Some of your military hours will count - the FW certainly and perhaps some of the RW if you're looking towards a CPL(A).
The airlines are some way off yet - being open and honest is your best bet.
Sorry that you didn't make it through the OCU - best of luck with whatever you decide to do.
