The 5 Heians and 5 Pinans started out (so I'm told) as one Kata. One student started a style doing the Kata one way, one student did it another.
Both styles though they were too difficult in their current form, and split the single Kata into 5 smaller Katas, giving us the 5 Heians and the 5 Pinans we have today.
Someone's been feeding you a line here. It may be that once upon a time in the 19th century the Pinans were derived from one kata (known as Channan), which was modified and split up into 5 sections. On the other hand I've never seen any convincing evidence that Channan kata actually existed. What is certain is that the Pinans were put together in the late 19th / early 20th century by Ankoh Itosu, possibly with some influence by one of his teachers, Sokon Matsumura, possibly with influences from other sources.
Heian is merely the name that Funakoshi chose for the Pinan kata when he 'Japanified' them, along with many other kata. As well as changing the name Funakoshi and his students also made significant changes to the manner in which the kata were practiced.

I haven't seen Bassai Sho (Little Bassai) to compare it to Bassai Dai (Big Bassai), but perhaps Sho was the first step to learning Dai.
My understanding, rightly or wrongly, is that Dai came first and was used as a template for producing the shorter Sho. As to why I couldn't say. Personally I find both Passai Dai and Passai Sho useful kata to practice. I believe a similar thing happened with Kusanka, resulting in the Shotokan kata Kanku Dai and Kanku Sho. I've never done the Sho version so I couldn't comment on it.
In answer to Susan's question about similar sequences in kata, there are many Okinawan kata that have similar sequences. But when you think about it this makes sense. Presumably each person who made up one of the classical kata was attempting to catalogue techniques or principles that he thought were of value. A kata, or at least a small group of kata, may be considered to represent the techniques of a self-contained self-defence system. So it makes sense that you will see some of the same themes in different kata. Different people made up different kata but considered some of the ideas to be important - so you'll see those same ideas expressed in different people's kata.
