Some errors with ShaderFX -> CGFX -> ShaderLab

So, I'm very much a noob when it comes to shaders, so could someone help me with this one?

I made a shader in ShaderFX, exported it to .cgfx-format and now I'm trying to manually port it to ShaderLab. Everything seems to go rather fine, except for these few errors it gives that seem to prevent some crucial parts of the shader from working.

Could someone check these errors and tell me what exactly they mean and how it would be best to try to fix them?
