Why is important translated as "bigger" here?

In French, important often describes the physical size, amount, or volume of something, rather than how "important" or significant it is. When talking about a salary (un salaire) or a sum of money, important means "large" or "substantial".

How does the comparison plus important que work?

To say "more [adjective] than" in French, you put the adjective between plus (more) and que (than). Here, plus important que literally means "more substantial than", which is the natural way to say "bigger than" when talking about money.

Why is it ton collègue? Is collègue always masculine?

The word collègue can be either masculine or feminine, depending on who you are talking about. Because the sentence uses ton (the masculine word for "your"), we know this specific colleague is male. If it were a female colleague, it would be ta collègue.
