I disagree with that idea because even if you know all the words in a language and you don´t know how to use that words you can´t speak a language at all. I think it is a better idea to learn phrases, and it is better if that phrases come from daily conversations not from text books. You need to learn what phrases are used in a specific context. I will recommend you instead of "1000 most common spoken words in spanish" a phrase book for travelers, not only you will learn a lot of words, but also you know how to use that words and in which contexts they are correct. I recommend you to go slow and repeat them many times until they are deep in your brain and you can use they naturally in a conversation.
