I would be grateful for information on published or available work in
this area.
I am thinking of an additive category as a ring with several objects, as
in Mitchell's well known paper. So in a sense am looking at 2-rings.
Thanks in anticipation.

Hi Ronnie,
There is the work of Matthieu Dupont, see his page
http://breckes.org/dom-en.html
His PhD thesis is on abelian categories in dimension 2.

Dear Ronnie,
You can find many good things in Mathieu Dupont's PhD thesis:

Dear Ronnie,
only just saw your message via David's reply.
Just for completeness it seems one should say that there is quite a
bit known about additive n-categories even for n all the way from 1 to
infinity -- they are called stable infinity-categories. Examples of
these are in particular given by modules over infinity-rings -- which
are maybe better known as ring spectra!
A modern entry point into the theory, from a category-theoretic point of view is
Jacob Lurie
Commutative algebra
http://arxiv.org/abs/math/0703204
But the basic elements and examples of the theory, such as
E-infinity-rings, A-infinity-algebras and their modules and module
categories are of course way older and quite classical even.
All the best
