Of course, without evaluating your son, it's impossible to tell if what he demonstrates is a serious, but normal spectrum child behavior problem, or the symptoms of a mental or emotional disorder (e.g., mood disorder). Regardless, it'll be imprtant to employ a systematic plan for managing the behavior - this would apply across the board. The implication of a mood disorder, for example, would be in relation to the use of some medication, in addition to managing the behavior. Children of this age typically have a hard time having limits set on their behavior, and they quickly become flooded with frustration and rage, and this results in tantrums. You can achieve a diagnosis of the problem, and a plan for managing the behavior, via consultation with a pediatric mental health professional. This would be a prudent step to take. Re: the behavior itself, many books about child rearing are not particularly useful because they tend to be overly general or theoretical. A sound approach to managing behavior is described in Lynn Clark's SOS: Help for Parents (published by Parents Press in Bowling Green, Kentucky.
