Amanda,
The Museum Association, based in London, publishes a complete guide to
careers in museums in the UK.  I believe it is free.  Just send a SASE
(230mm x 160mm) to Careers in Museums, Publication Sales, Museums
Association, 42 Clerkenwell Close, London ECIR 0PA.  I believe they can be
reached by e-mail also.  Contact: John Wellington, Membership Officer at
[log in to unmask]

Hope this helps.  I, too, am a graduate student seeking a career
opportunities in the UK.  Maybe I'll see you there!
