3-6 are beign worked on as we speak, untill the next patch is realesed and the NDA restriction is lifted on the work beign done I can say nothign else.
On 2. if memory serves me correctly the USA declares war when it's WE reaches 100. This is antoher thing that is constantly tweaked int he game as well. If you are editing the game file, try setting a negative WE value for the US (this is allowed) and this will slow down US war entry.
On1, you need combat transport procedure docterine (or something like that) to build transports. I will makr this a bug becuase Canada cannot do this is 1939 which is clearly a problem.
