Actually that all rather made sense to me. I mean it's not like he cared to learn about analyzing stocks as it didn't enhance his crime-fighting skills. As far as the detonator I'm sure he only had limited knowledge of detonation and militaristic devices of that nature and he was kind of short on time and needed to focus on other things.
The fingerprinting powders made sense because he was sort of a "detective" and the computer stuff also sense he had enough time to browse the web lol.
