Re-insulating Attic

Hi All,
I have some weird kind of paper honeycomb insulation in my attic. Any seen this stuff before? I figure it's going to be better to rip it all out and replace it with fiberglass insulation instead of just putting new on top of it. Does this make sense?
I'm in NJ and use Oil Heat.

Do i need to install something like "Owens Corning RAFT-R-MATE Attic Rafter Vents"

A portion of the attic has a flooring installed. Would it be acceptable to just insulate under it, since i do wanna take it out completely.

Since the joists look to be 2X6 and 16" on center i was going to use a faced R20 next to the ceiling and then another r20+ unfaced in the opposite direction, where the flooring is not.

Any advise or comments greatly appreciated.

The way you intend to insulate the attic is fine but I do suggest that you go to the above stated webpage. It is a fairly easy to read lecture on the purposes and the ways to provide adequate attic ventilation.
