Hmm, thats a weird request...
Sorry, I meant "Flood" not "Flush".
Flood (Red in the screenshot) is a command in the weightpainting tool . It allows you to give all the selected vertices the same amount of weight (Yellow)

So what you need to do is:
1) combine your meshes and delete history on the new mesh
2) select all the joints and the new mesh and use the Skin->Bind Skin command, Heatmap mode will probably give you the best result in this case.
3) You open the weightpaint tool.
4) For each piece of armor, you select the joint that is corresponding to it in the weightpaint tool joint list (Blue), go to select mode (Green), and in vertexselection mode you doubleclick on one of the vertices, this should select the whole piece of armor.
5) You set the Value and Opacitiy (Yellow) to 1 and hit "Flood" (Red), this will make the entire piece of armor follow the joint you specified.
This will save you the time of painting all those armor pieces and you can probably use the same for the head and hair as well. after that you'll just be left to do the pieces that deform, like the body, the coat and the boots. You'll have to weightpaint those by hand I'm affraid, but hopefully the default skinbinding will already be pretty close.
I hope this helps!
