"svn checkout" creates a working copy on your local computer (or
wherever you check out) containing whatever's in the repository
location you specified. Example: if you want to have the latest
source code of Subversion itself:
svn checkout http://svn.collab.net/repos/svn/trunk svn-trunk-wc
If changes have occurred in the repository since you checked out,
"svn update" will bring those changes from the repository into your
working copy. Example:
svn update svn-trunk-wc
"svn commit" is for sending changes you've made in your local working
copy back to the repository. Example:
svn commit svn-trunk-wc
"svn export" creates a directory that contains the files from your
working copy path or from your repository URL, without all the
administrative Subversion data that makes it a working copy. This
directory cannot be used to pull new changes from the repository or
to push your changes to the repository. Example:
svn export svn-trunk-wc svn-trunk-export
or:
svn export http://svn.collab.net/repos/svn/trunk svn-trunk-export
This should all be explained fairly well in the excellent book which
we all still think you should read. :)

When you first put code into the repository, you might use "svn
import" to import an existing unversioned directory into some place
in the repository. Once you've done this, you discard the directory
you imported, and check out a working copy.
Or, if you want the directory you're importing to become a working
copy, then you don't use "svn import" at all; instead, you do a so-
called "in-place import" described here:

Yes. The repository is a kind of database. You cannot see its
contents without using a client program designed to do so (e.g. a
Subversion client).
To make changes to its contents, you want to get a working copy, if
you want to do Subversion operations like update and commit on it, or
you could get an export if you don't care to be able to do those things.

Great!
