I'd interpret it to mean that he felt he wasn't going to be a vice president for very long. The "also" suggests that the VP job was of lesser importance than some other job. Perhaps he knew he was going to be promoted so rapidly that there would be little opportunity to use the cards.

Here it means that since he had an an important title he assumed that everyone would know who he was.

This means something like "didn't take the trouble of printing the cards", didn't care about doing this.
