No, I would say this is a trap, a side-trail that does not lead to the goal.
It looks attractive to the ego, because it stimulates certain hope in us, a hope to get closer to the Truth -- but this is a false hope. There is a Pali term,
papañca, which can be translated as "conceptual bullshit". This is the danger here, getting caught up in quasi-intellectual masturbation.
The Truth is known by realized teachers, this is whom we must seek. Teachers show us how theoretical dharma maps to real life. The only reason to prefer the books over teachers' interpretations, is if you don't trust the teachers. If this is the case, then you should take a good look inside yourself and ask: "why do I assume that no one really understands Dharma? Could it be a projection of my distrust/aversion to this world with its people and values?" Surrendering yourself to a teacher helps.
That said, it is tremendously useful to know the main terminology. So I keep my Sanskrit and Pali dictionary links on my Google Chrome toolbar, and use them all the time. You can learn a lot from understanding the raw meaning, and the story behind, some words.
There are people who were able to turn the trap into a blessing. Take Ven. Bhikkhu Bodhi for example (the famous translator of Nikayas into English) - he got caught up in a fly trap, but because he was so determined, he was able to tear through all words, understand the meaning, and get to the nectar -- while benefiting all of us. But unless you are a super-geek like him (I respectfully bow at his feet!) -- your time is much better spent putting dharma to practice.
