See you second question.

Not (yet).  Right now, you have to do

git submodule init
git submodule update

after you clone to fetch and check-out all (first-level) submodules.

Yes. No. Yes.
In fact, only the "git submodule" subcommand are affected by a
"git submodule init".  Doing a "git submodule update" will actually
check out the submodules and from then on, the HEAD of this checked-out
submodule will be considered the content of the submodule in
the working tree of the supermodule.

It only has to be specified in .git/config.
The value in .gitmodules (if present) is used by "git submodule init"
as a default value for the one in .git/config.
