Documentation you might want to read: 

* "Git User's Manual", distributed with Git (installed at least on
  Linux at $sharedir/doc/git-$version/user-manual.html), also at
  http://www.kernel.org/pub/software/scm/git/docs/user-manual.html

* "The Git Community Book", available at
  http://book.git-scm.com/

* "Pro Git.  Professional version control", available at
  http://progit.org/book/

You should create a new repository for each project.  In git each
commit is about state of whole repository.


If you have single unrelated files, you might want to consider using
Zit tool (see http://git.or.cz/gitwiki/InterfacesFrontendsAndTools for
details), but beware that it is in early stages of development.

(Although if you choose one big repository, you can split it later
with some effort using git-filter-branch (or git-split somewhere in
mailing list archives) if you didn't publish your repositories).

"git add ." would add _all_ new not ignored files, and would stage all
changed files.  But you would have to be sure that all files you don't
want to be comitted, like generated files (*.o, *.log,...) and backup
files of your editor (*~ or *.bak), are ignored using .gitignore
(usually for generated files) and .git/info/excludes or
core.excludesFile (usually for specific patterns like backup files).

Most git commands take subdirectory they are in into consideration
when acting.  "git add <filename>" in subdirectory works as expected.

Note that some commands need to have '.' as filename / pattern to be
limited to current subdirectory / act on current directory.
