Theres a first time...
 

for everything...*sigh*. I have a few questions regarding the Japanese language, but first I should say what i already know. I can read katakana (i know most if not all of the symbols/combinations of katakana), and a little hiragana. I've picked up a few random words from SRW games and anime. Thats pretty much it... so, question time.

Are there words that can only be written in hiragana, or should i just go to a kanji dictionary for vocabulary building? If there are words that are only written in hiragana, are there any word banks with all of them in it?

I need something that tells me how particle words work (as detailed about it as possible) as the information i already have on it is shallow and i can't understand it (such as calling one of them a softener, showing a single sentence example, and moving on).

Some good resources about Japanese grammar. Again, as detailed as possible.

Verb conjugations. Again, the resource i already have just isn't detailed enough and i don't understand what it means most of the time.

Whatever the best kanji database is that you can think of.

Anything you think I missed.

Edit: Oh, and I should mention that I'm doing this alone/self-teaching/whatever you wanna call it.

well most of these questions have been answered recently in posts, so please look through them. but at the end of the day the ebst advice i can give you is get a good beginners book.

i really can't understand how people wanting to learn the language aren't about to afford enough for a decent text book. i have at least 12 books myself.

as for words written in hiragana, there are words that are commonly written in hiragana only such as 'thank you': ありがとう but it can also be written in kanji: 有難う the thing is children's books start off with just hiragana and as they learn the kanji they progress to include kanji. it would be a difficult task for you to start of straight into kanji for learning vocabulary. leave it for later, kanji is going to take you a lot of time to master a decent level.

so for example you should learn sentences that are simple like below in hiragana first, then as you learn the kanji you can fill them in

i want to go to the park
こうえんへいきたい - no kanji
こうえんへ行きたい - started learning
公園へ行きたい - continued learning, starting to be able to use more and more.

Yeah, I noticed the stuff in the other posts. I spent a while writing down addresses (firefox erases my bookmarks frequently). Thanks for the help though, that really cleared up alot.
