Vintage 9 Piece Paine Dining Room Set

I bought this dining room set from the owners son. It appears to be a matching set consisting of a 64x42 table with 2 12" leafs 6 chairs(2 have arms),side board 62x20x33 with 5 drawers(3 across the top,2 underneath them down the middle with a door on either side for more storage)and sits on 5"curved legs with scrolled feet. The corner hutch is one piece but looks like 2, storage with 2 doors at the bottom with a 42" china cabinet above with 2 glass front doors 38x18x72, it too sits on the same matching feet...the table has the the same legs.
The stain on the wood is a pretty medium color but I don't know what type of wood it is. The style to me looks french country with the type of detail and the slight bowing to the middle drawers on the side board.
Any information you could give me about the year it was made, the type of wood and its value would be so appreciated
The set does have some scratches on it and some water marks on the table but other than that it is solid and in great shape. Guess I could also use some advice as to how to best clean and wax the wood on this set.
The pictures of the set are on my blogspot..makeminechicboutique.blogspot.com I will try to copy the link here..http://makeminechicboutique.blogspot.com/
