Depends on how you change it, but the default works just fine, you don't
need to adjust it. If you want to read more about it see

A meta-package is a package that exists only to depend on other
packages. In the case of linux-image-<flavour> it will depend on the
current kernel from the *same* release.
Other meta-packages are used to install entire collections of software,
or ensure automatic transitions when package names change (also called
transition or dummy packages).

Depends on what you want to achieve. If you somehow need (e.g. for
hardware support) a newer kernel than available in stable I would advise
you install linux-image-<flavour> from backports:
apt-get install -t wheezy-backports linux-image-amd64
(you didn't mention which flavour you are using so I guessed amd64)
This will make sure you're always upgraded to the current kernel in
backports. Do make sure to keep the previous backports kernel around, in
case you have troubles with the newer kernel.
However, if you don't really need a newer kernel you might as well stay
with stable. Just because you can doesn't mean you have to install a
newer one.

This is out of your hands. As a user you can only choose between
installing linux-image-<flavour> from stable, which will always depend
on the latest stable kernel, or the version from backports, which will
always depend on the latest backports kernel.
You haven't yet stated why you need the backports kernel, but if you
want to keep using it install the backports meta-package.
The stable kernel will still be upgraded until an ABI bump happens
(which may as well never happen for the lifetime of wheezy). It is a
good idea to subscribe to the debian-security-announce mailing list,
such changes will be announced there (along with all other security
updates).
Also, if you only keep it around as a double insurance it doesn't matter
so much if it's not up-to-date, as long as it boots correctly. Just
remember to update it if you use it for more than just a recovery boot.
Kind regards,
Andrei
