The kinetic energy I am interested in is that involved in forward motion through space. What is the relationship between these two motions?
-
They are both conserved. So when rigid gravitational masses move past each other, they will follow curved paths such that the total angular momentum and kinetic energy remain constant.

Thanks Alan. I need to do a bit more reading up on this but just wanted an initial response to confirm my initial thoughts.

Jeff. Have you studied Lagrangian or Hamiltonian mechanics as of yet? If so then you'd have known the answer to this question. That's the benefit of studying various forms of mechanics.
You want a relationship between K and p, right?
p = mv
Q.E.D.

I have studied neither yet but I need to get round to that. Thanks for the equations they will be useful. Do you have any recommendations for textbooks on the above mentioned mechanics?

I'm happy to see that those relationship were what you had in mind!
The textbooks below are all very good and can be downloaded from the internet at the URLs I gave below the title for free. I'm sure you'll enjoy them. As always, I'm at your disposal. :)
The term Analytical Mechanics refers to the mechanics of Lagrangian and Hamiltonian Mechanics. See: http://en.wikipedia.org/wiki/Analytical_mechanics
One typically uses Variational principles in working with these areas of classical mechanics.
The Variational Principles of Mechanics by Cornelius Lanczos (1970) is famous for this branch of mechanics. It's quite well-known.
