    Okay, I'm gonna ask this question I've had in my head for a while.
    In the texture box, whats this world/face align thing for? what does it actually do?

    it's to do with witch orientation the texture is calculated from. a texture with world orientation but not face will be flipped horizontally (because you are effectively seeing the "back" of the texture). face is usually a safer option, as it keeps textures in correct scale on faces that sit at an angle to the grid.
    Try making a large brush that sits like a big right angle triangle when viewed in the top down view. texture it with something like a dev texture (one that repeats a pattern) and swap between face and world alignment. With world will be stretched in the x axis (relative to the texture) and with face the texture will look normal.

    I've always wondered, actually, is there any way to get the texture to show up backwards without aligning it to World (or if it's positioned in such a way that doing that doesn't help)?

    Negative scales will mirror a texture.

    Ah, thats what it is.
    Another thing, sometimes both boxes are ticked and i cant untick them, or both are ticked with one (usually world) greyed out. What does this mean?

    when both are ticked (and the normal colour) it means the face is aligned to the world. its not a bad thing. When one or both is/are greyed out, it means you have selected 2 or more faces with at least one aligned to something different.
    Let me explain that better. Say you select either side of a wall. Unless you have changed which alignment they follow, one side will be aligned to the world, and the other to both the world and the face. this would cause the "face" check box to show grey, because not all of the faces selected are aligned to it.
