Questions about the Messiah…

I am doing some lecture prep and research on early Jewish conceptions of the Messiah.

1. Can anyone recommend good resources (preferably not too monograph-y) on early Jewish concepts of the Messiah?  Is there a classic that is still accurate?  Who are the movers and shakers in this area?

2. Was the Messiah ever called or linked to the ‘image of God’ in early Jewish texts?

Thanks!
