Paul,
I will assume that you already know the basic process of shifting this type of transmission, since you state you have read past threads. So let me emphasize what I think is the most important aspect of the process, and that is the importance of matching the engine rpm with what it will be when you put the transmission in the next gear. You can do the clutch thing correctly, but if you over rev (or under rev)the engine, you will get clashing of the gears as you attempt to slide the shifter into the next gear.
Regarding a cold start, you should use the throttle cable to get a bit more gas into the carb. Even the owner's manual recommends pulling the throttle cable out a bit on a cold start.
When I first got my '42 I began looking for a three speed synchromesh tranny to replace the crashbox but now I am proficient enough, and I enjoy the challenge, that I feel it is part of the charm of driving the truck.
