Practical DX Transforms.

Hello, I have two questions: A: How should I organize my DirectX transformation code for optimal useability and speed? I currently have a rather messy Object3D class which deals with translations and it needs to be inherited by anything that wants to 'move' around. Also, I presume that the camera should stay still (at the origin pointing down an axis); so how would I make it so that I could efficiently make things move opposite to the camera's 'movement'? B: Secondly, I wrote an X file mesh wrapper and although it takes practically all of the code for loading and rendering the mesh from the DirectX doc tutorial #6, it loads the mesh fine, but no texture shows; even though it looks like the code should support it. (The DX mesh veiwer shows the same mesh with a texture, and it also appears that the X files also hold their own textures, is this true?) and just for reference, here is my X file loading source:

DXGeomBuffer::DXGeomBuffer(char* file, IDirect3DDevice9* dxDevice, IDirect3D9* dxObject)  
{
	if(dxDevice != NULL)
		dx3DDevice = dxDevice;
	if(dxObject != NULL)
		dx3DObject = dxObject; 

ID3DXBuffer* pMatBuffer;  
	// Load the mesh from the specified file
if( FAILED( D3DXLoadMeshFromX(file , D3DXMESH_SYSTEMMEM, 
            dxDevice, NULL, &pMatBuffer, NULL,
			&numMaterials, &pMesh ) ) )
{
	return; 
}
//Get Material buffer pointer.
D3DXMATERIAL*		d3dxMaterials = (D3DXMATERIAL*)pMatBuffer->GetBufferPointer();

//Create arrays for material and texture information.
D3DMATERIAL9*		g_pMeshMaterials = new D3DMATERIAL9[numMaterials];
LPDIRECT3DTEXTURE9*	g_pMeshTextures  = new LPDIRECT3DTEXTURE9[numMaterials];

//Load the data into those arrays. 
for(unsigned int i = 0; i < numMaterials; i++)
{
	g_pMeshMaterials = d3dxMaterials.MatD3D;
	g_pMeshMaterials.Ambient = g_pMeshMaterials.Diffuse;
	if( FAILED( D3DXCreateTextureFromFile( dx3DDevice, d3dxMaterials.pTextureFilename, &g_pMeshTextures ) ) )
		g_pMeshTextures = NULL;
}

It borrows quite heavily from the DX tutorial #6.
