From reading/speaking in Mandarin to writing

I am currently in the process of learning how to write in Chinese. The more and more i look into it, the more easier the strokes become. Because I have already learned a few characters, I am able to read to a degree by identifying a character and it's meaning. The part is using the characters that I already memorized to practice writing, because I can't remember the exact stroke order when I sit down and try to write by memory. This is due primarily to the fact that up until now, i have not made a valiant effort at training my brain to write in chinese characters. Does anyone have any tips/advice? Any recommendations for books?

memorizing the hiragana and katakana Does anyone know a good website that lists and neatly organizes Japanese katakana/hiragana with audio files of the syllables?

Typing in Japanese I tried using the Japanese IME I installed, but it was somewhat confusing. When I entered the romaji for a word (speak, for example), the right hiragana wasn't being shown. Then, when I pressed the spacebar, it turned to kanji. The IME isn't corrupted or anything, I just don't know how to use it properly. Can someone tell me what I'm doing wrong?

Online Japanese Dictionary Can anyone give me a list of online dictionaries for Japanese that they're aware of?

日语和汉语 I'm looking into studying Japanese along with my Mandarin studies. Can someone give me some info on the Japanese grammar? I understand a few things (like how there are no tones, and how Japanese has katakana, hiragana, and kanji). Does Japanese have a similar grammar/word order to Mandarin? Does Japanese not have any verb conjugations like Mandarin?
