I guess this must happen all the time and I just have not noticed, but I see in 这个坏了，你去买个新的吧, that we just use 个 ge (a measure word/individual) by itself without 一 yī or any other number. Is this common and are we always to understand one if no number is stated? If so, could the 一 be dropped from the sentence, “爸爸给我买了一本书”? Now I see that I have often used 个 alone in 这个.

你说得对，in spoken language, it is common dropping the 一 before mesure words. The sentence "爸爸给我买了一本书" 也可以说 “爸爸给我买了本书”。
Here are some more examples:
