The name Elohim is indeed plural. I think it only appears in Genesis. Most English translations simply translate this as "God", but most English translations of Christian texts are bad translations of bad translations.
As I understand it, the Elohim were supposedly a group of divine beings that did the grunt work in genesis. A bit like angelic contractors, but without their bum cracks hanging out.
I think you have to go back to really early or even pre-christian texts to find out anything about it anyway.
