Good luck Tom, Im sure that pumping will go really well for you.
I also hope that given everything else you are dealing with at the moment this gives you a little lift. Remember not to be too hard on yourself if you dont achieve the numbers you crave for a little while. With all the stress you are under it would be hard to keep them tight on a well defined MDI reguime. It takes time, but I hope you can enjoy it.
If there is anything I can do to help you out, please just ask (but I have a funny feeling you will take to this like a duck to water!) but we are always here should you need any advice.
Take care mate.
