How different wing fuselage attachment looks when it comes to composite wing ( composite spar, skin) or it is just metal to composite replacement ..(I suppose some parts like splices /cruciform's ,root rib still be in metal)

Any lesson learnt from B787 composite wing??

Yup.
Make it stronger by a factor of two, at the attachment location.
The first forty 787's to be delivered, will be returned to Boeing at the first heavy check scheduled, for rework of the attachment area (among other items)...so I have been told by a Boeing rep, recently.

Why not rework the attachment area now while they are still at Boeing being tested/assembled? Why wait for the first heavy check?
