In Need of Help - Learning Japanese

Hello, I am Yuuki and I know how to speak a little bit of Japanese. I do not know any kanji, and I can spot very few Hiragana and Katakana.

The point is, I would like some help learning Japanese. I would like to become fluent enough that I would not look stupid if I ever visted Japan. Which, I hope to visit there one day.

So please help! Arigato!
