Predictions: Stupid Fast

So I just started reading this book titled Stupid Fast, and there have already been some interesting details that have been shared. One such detail being that Felton Reinstein, the main character, his dad committed suicide when Felton was only 5 years old. I feel that this piece of information will be important later on in the story because he constantly keeps referencing his dad. Also Felton talks about the issues he has had in his life like the anxiety attacks only in school, getting DQ'd (Disqualified) at regionals for track and also once again, his dad.

Some predictions that I have are that Felton will later get a second opportunity to qualify for state and instead of getting disqualified, he will win and move on to the state meets. Another prediction that I have is that he will end up playing high school football because the front cover of the book shows him in a football locker room with shoulder pads on. A third prediction that I have is that his best friend Gus, will not return from Venezuela because his grandma is terminally ill. Due to the fact that she is ill, I feel Gus's mother will want to stay in Venezuela for a while to be with her family. Also due to the inconvenience that Gus is out of the country for the summer Felton has to do his paper route and finds out that a new family is renting the house and Felton then has to deliver paper's to that house as well. But that's beside the point. The point being that my final prediction is that Felton will fall in love with the girl that is staying in Gus's house because he describes her as being beautiful and pleasurable to look at.

A few question that I have come across my mind are, why is Felton's dad committing suicide relevant to any part of the story?, or is the author giving us background information for later in the novel? Also, will there be a relationship between the new girl and Felton, and what will happen if Gus's family does move back into the house?
