Well it seems only an activation flag, so no specific code
So, i this it should a code like that:

case D3DRS_WRAP0:
  TRACE("Wrap Activation Flag for TextureStage 0 to %04x (QRST)\n", (DWORD) Value);	
  break;

and in TSS wraping mngt (IDirect3DDevice8Impl_SetTextureStageState):

switch (Type) {
case D3DTSS_ADDRESSU:
  if (D3DTADDRESS_WRAP != Value || (This->UpdateStateBlock->renderstate[D3DRS_WRAP0 + Stage] & D3DWRAPCOORD_0)) {
    TRACE("Setting WRAP_S to %d for %x\n", wrapParm, This->StateBlock->textureDimensions[Stage]); glTexParameteri(This->StateBlock->textureDimensions[Stage], GL_TEXTURE_WRAP_S, wrapParm);
    checkGLcall("glTexParameteri(..., GL_TEXTURE_WRAP_S, wrapParm)");
  }
  break;
case D3DTSS_ADDRESSV:
  if (D3DTADDRESS_WRAP != Value || (This->UpdateStateBlock->renderstate[D3DRS_WRAP0 + Stage] & D3DWRAPCOORD_1)) {
    TRACE("Setting WRAP_T to %d for %x\n", wrapParm, This->StateBlock->textureDimensions[Stage]);
    glTexParameteri(This->StateBlock->textureDimensions[Stage], GL_TEXTURE_WRAP_T, wrapParm);
    checkGLcall("glTexParameteri(..., GL_TEXTURE_WRAP_T, wrapParm)");
  }
  break;
case D3DTSS_ADDRESSW:
  if (D3DTADDRESS_WRAP != Value || (This->UpdateStateBlock->renderstate[D3DRS_WRAP0 + Stage] & D3DWRAPCOORD_2)) {
    TRACE("Setting WRAP_R to %d for %x\n", wrapParm, This->StateBlock->textureDimensions[Stage]);
    glTexParameteri(This->StateBlock->textureDimensions[Stage], GL_TEXTURE_WRAP_R, wrapParm);
    checkGLcall("glTexParameteri(..., GL_TEXTURE_WRAP_R, wrapParm)");
  }
  break;
default: /* nop */
  break; /** stupic compilator */
}

But i don't know if its valid to call SetTextureStageState(...D3DTADDRESS_WRAP) before SetRenderState(...D3DWRAP_U...) (you should test) 
If you look at http://if.dynsite.net/t-pot/program/28_bump/bg_cpp_ps.html
they do it

Yes: 3 param U/V/W

I think its used for cube texture (need face selection)
but don't worry for now

They seems deprecated since DX8.1 (maybe never implemented)
D3DRS_POSITIONORDER             = 172,
D3DRS_NORMALORDER               = 173,
