Sprites I've been using a single LPD3DXSPRITE to draw all my sprites in one go. Would it be faster to use seperate objects or as I have just seen an implementation of; Draw a quad in screen coordinates and UV map the texture over it?

Probably not. It depends on the exact situation, how many sprites you're drawing, etc. If you have multiple ID3DXSprite objects, you have multiple draw calls, so using one sprite object will always be faster than multiple ones. You can sometimes get better performance by drawing quads yourself, but there's no point in doing it unless you've profiled and found that your sprite rendering is a bottleneck.
