If I were a beginner learner in English , I wouldn't learn all of English roots(radicals) at the very beginning. The same way goes for Chinese . But , I suggest you to learn most of the pronunciations before the further learning. Just personal viewpoint.

I would not suggest that you go out of your way to learn the 部首 on their own. I think the most effective way if learning Chinese is to follow the standard textbooks written especially for foreign learners. These are extremely systematic, and you learn to read and write everything in context. Nothing is learned in a robotic memorisation vacuum. Just learn what the textbooks say you should learn. The 部首 come individually over time in an orderly manner as you complete the whole set of textbooks. The sets published by 北大 and 北语 - 对外汉语教材 - are the best.

I mostly agree with Nick. I would also like to add that breaking up that 214 by familiarizing yourself with 50 - 55 radicals (with audio if you prefer) repeatedly Monday to Friday using an app for your phone while commuting or waiting in line for whatever will make it less boring. It also will help you later on when you start learning compound characters and phrases. By then, you will have a better idea of what makes up that character or characters you're learning. Just my 2 cents (from someone who's also learning Mandarin)

Thank you everyone. You all agreed that it is not very effective to learn radicals alone without context. After your explanations I also can see why so. Thanks again.
