Life In 19x19

I am serious about Go, and I want to be the best I possibly can. I was wondering if anyone had any tips, info, ideas, etc. on how to be able to study Go in Japan, China, or Korea. How can I apply for classes, and other things like that? How do I go about at doing this?

How does one count points, territory, etc. How do you know what is your territory and what is not, and how can you add this up in your mind during a game to get a rough estimate on who is winning?

Are there any resources or things in can do to practice my skills in reading ahead during a game to improve my abilities?

Forgive me, but I'm still learning the game. My question is, how do I choose which Joseki I want to use, and how do I know when the Joseki has ended and I have to start thinking on my own? Also, and links to Joseki resources will help a lot too.
Thanks

I was wondering if you could be kind enough to provide me with some links to videos, maybe from YouTube or other Go websites, that have Go lessons, or commented games, etc. I'm new to Go, and I really want to improve.

I am intent on mastering Go, but unfortunately I don't live in Japan, Korea, or China, which are the Go capitals of the world, and with the predomently Cuban population of Miami, I'm not ideally situated.
Regardless, however, I was hoping the someone would know if there are any classes in the Miami ...
