You mean hiragana? Try smart.fm.... it's great!
They have hiragana, katakana, and kanji lists.
They also have lists for learning basic phrases, words, etc.
Send me a message if you're interested, and I'll send links to courses that would be helpful... ^-^
BTW, "Arigatou gozaimasu". ありがとうございます
Gambatte! 頑張って <with kanji, as it's actually written>
がんばって <hiragana only> Try your best! <Kinda like we use "Good luck!">
