Is that hard to wait having a decent knowledge before proposing things ? Wanted to help is welcomed but right now you don't know what you're doing... You should be able to see yourself now.

MSG_PVS/MSG_PAS still not fixed, nor floating vectors.
For the first Exolent told you what to do, for the second, see EngFunc_ constants, it supports float.
About how to organize things, it's up to you, I don't have suggestions.
