Welcome to the forum, I hope you'll enjoy your stay
2. Wikipedia has all you need to know:
Japanese writing system - Wikipedia, the free encyclopedia
3. Do you mean channels that teach the language to foreigners, or random by-Japanese-for-Japanese channels for general listening practice?
4. I use
Jisho as my main dictionary. You'll need to know hiragana (one of the Japanese writing systems) to be able to read words' pronunciations.
5.
Guide to Japanese seems to be pretty popular with learners. I haven't used it for studying myself, but on the few occasions that I did visit it, I found that it gives nice succinct descriptions of grammar concepts.
6. Popular beginner's textbooks include Genki and Minna no Nihongo (I used Genki myself and quite liked it).
7. You can watch Japanese news channels over here:
動画ニュース連続再生 - NetTV-News on the Web
If you're going to watch anime, do so without (English) subtitles. The same goes for other media: either have Japanese subtitles or no subtitles at all, so your brain doesn't even get the chance to be lazy and ignore what's being said.
As a general guide for listening practice, I'd say: if you suddenly feel unusually tired after listening for a while, that's a sign it's working. If not, that's a sign the material is either too hard (you're barely picking up anything at all) or too easy (you can understand almost everything as effortlessly as your native language).
As for "no teacher nearby": online courses, where you get into contact with a remote teacher via voice chat, also exist.
