If your main goal is to speak and listen to Japanese the kanji probably aren’t a big deal. But if your goal is to read Japanese the sooner you learn how to use a kanji dictionary the better. Being able to look words up on demand is a lot easier than having to memorize 2,000 kanji before even thinking about reading your first Japanese comic or news article.
