I suggest you use a free lessons website like www.howtostudykorean.com and/or www.talktomeinkorean.com . I'm somewhat new to the Korean language as well, and they both have been working wonders for me! They have leveled, thorough, and easy grammar lessons and vocab and they pretty much take you in from the very beginning and show you where you need to go until you're an advanced speaker! I loooove them both! Good luck, and have fun on your Korean journey!

I think you could learn some basic grammar first. Like conjugating for tenses (in various speech levels), copula 이다, 있다/ 없다. Actually this is what almost every book for learning Korean would introduce you to at the beginning. Along with this you learn words/ basic expressions. From my own experience, what I think is crucial but never fully explained (but rather divided into "lesson" system) by such books are "(으)ㄹ/ ㄴ/ 는". I don't know what it is actually called (there are several names depending on book/ site) These "endings" are something you use: ▪ to indicate Tenses of the Action and Descriptive verbs (adjectives) ▪ to make D.Verb describe nouns Overall they are a foundation of every clausal conjunctives and so. When I came to know about this "foundation" all grammar seemed much simpler than I thought. Imo what is also important: Irregular conjunction of the verbs And of course all particles!
