Liquid - have a look at :
http://www.dispatcher.org/
It's a US site, but is the 'bible' for dispatching. Note though that 'dispatch' in the US is the same as 'Ops' in the UK. UK dispatchers are the guys n gals that control the a/c turnrounds.
Hope this makes sense ?!
Pay will be totally dependant on experience, in your case I would have thought you'd be looking around £12K-£14K ish depending again on where you end up.
As Keyboard says - formal quals in UK aren't pre-requisite, but any aviation related stuff will be a real plus ( eg PPL / C&G etc. ) In the US you must have a formal FAA license for dispatching - which is expensive.
