A Few Questions

[JimmySeal]

Not wanting to use a textbook makes me obnoxious?

No, this exchange makes you obnoxious:

As I intimated earlier, you'll be far better off if you learn from a structured textbook. This stuff is easier to pick up when it is presented in some sort of logical order with the stuff that comes earlier building a foundation for what comes later. You're leap-frogging and dashing about aimlessly among various grammar points succeeding mainly in frustrating and perplexing yourself mostly because of that approach, and not due to the language itself.

Thing is, I don't intend on buying a textbook (or anything for that matter).

Turning your nose up at sound advice without so much as an explanation why.

Apologies if the comment was taken that way, but that wasn't my intention. But I shouldn't have had to explain further - the simple point here is that I never intended on buying anything to learn the language, and that's what I stated.

Want a good site? Jplang. But I don't know if it will be good for complete novice without any tutor.

Just a quick correction.
koohii desu "It is coffee"
koohii deshita "It was coffee"
koohii de ha nai (koohii de ha arimasen) "It is not coffee"
koohii de ha arimasen deshita "It was not coffee"
There is coffee "koohii ga arimasu"
There was coffee "koohii ga arimashita"
There is no coffee "koohii ga arimasen"
There was no coffee "koohii ga arimasen deshita"

domo! Sorry I was having a tough time trying to explain "desu" ^^;;

How about this site?
"Tae Kim's Japanese guide to Japanese grammar"
Learn Japanese – Tae Kim's Guide to Learning Japanese

Being a native speaker I cannot tell whether it is good or not from experience, but as far as I take a look at many pages of this site, it does not seem to be too complicated and give a lot of examples, I think it will be helpful for learners, especially for beginners.
