OK, I feel like I have enough experience in drilling myself in a difficult-as-shit language over the past couple of years to give you some advice.
You're going about it all wrong. You may decipher Korean grammar this way, but you're never actually going to learn the language going about it like this. First, focus on listening as much as possible. Don't even actively try to understand what you're listening to, just immerse yourself in Korean. Set aside 1 hour minimum a day where you're going to listen to only Korean. No English or French (reading or listening) whatsoever. It may feel like you're wasting time, but passive listening will actually gradually increase your comprehension, though it is a slow process. Fortunately for you this just means you need to seek out Korean-casted SC matches instead of English-casted ones. First your ability to pick out sounds will gradually increase, and one day you'll go "oh shit I'm not grasping for sounds anymore". Then one day you'll go "holy shit I understood that word awesome." Then, "holy shit I understood that sentence, goddamn."
You will of course need to do active study on top of this, but the passive listening is frankly more important at first. If you have only enough time in the day to listen for an hour or study grammar for an hour, your choice is listening, or not learning anything that will stick.
So, you started listening to a lot of Korean and find yourself with enough time to study on top of your listening (or while you're listening). I don't know about the quality of any of these sites, but searching google for "learn korean" came up with a number of them. Unfortunately Rosetta stone sucks for East Asian Languages, and Duolingo doesn't have a Korean program, but there are some resources out there. If you feel more comfortable with a textbook, I'm sure there are korean textbooks out there you can buy for your study.
Now, whatever you're using as your primary study guide, get this:
http://www.ankisrs.comFor studying, get this program and start inputting sentences from your study guides and things your friends have translated for you, etc, and start doing spaced repetition flashcard reps. Pick one focus per flashcard (phonetic reading, meaning of a word, meaning of a whole sentence, change in formality... etc. I don't know Korean so I'm kinda guessing at the specifics. This is where a Korean textbook will come in handy). If you have audio files handy you can also put them into the flashcard system. That's going to get you way farther in learning a language than sitting around overanalyzing individual sentences your friends translated ever will.
Think about it like learning how to macro vs. the metagame analysis you did for individual SC2 units a couple years back. Drilling macro and learning to do it without thinking about it too hard and without missing things like pylons or key buildings (which is what spaced repetition flashcards, frequent listening/reading and eventually frequent speaking/writing are equivalent to), is going to get a bronze player (as far as Korean goes, this is you) much, much farther than decoding individual sentences / unit names and then never revisiting them or trying to put them into a larger context (metagame analysis in this metaphor). The only place this metaphor breaks down is that passively watching SC2 games won't improve your play at all, but that's why it's a metaphor.
Good luck with the Korean. Compared to Japanese, it sounds like French when compared to English. Also Reavers.
