Is this an inner/outer dc block? in other words, does it block dc through the center conductor and the through the outer shield?

There is no way for it to block power through the outer shield as there is no insulator on the exterior metal. Power is only blocked through the center connection.

Does this go in between the lna and the sdr or betwen the lna and the antenna ?

Hi, it depends on what you are using it for! If you contact us at support.nooelec.com with details we'll be happy to help, thanks :)

Is this what you use between noaa and goes lnas and the sdrs nooelec makes? is it enough to use the power plugs for the lna's?

Its to protect your SDR from the power an LNA uses that might feed back through the antenna connection. For that it's worked great for me.
