You could start the ATPL's distance but I would advise that you fly as much as poss during summer 2009 and 2010 to try and get a total 150 hours by the time you have sat all 14 exams. So as you can start a CPL course.
By the way, do your night rating in the winter now or at the end of 2009. Long dark nights and you might be lucky to do it all in one night or 2 at a push.
If your going to be doing it all part time, you will need to think about your hour building. If you pass all 14 exams, you may be in a rush to hour build before those exams lapse (36 months from last exam passed I think) if you have not passed an IR flight test
Plan it out, start ATPL's distance now (Bristol Ground School) and plan to do stage 1 brush up and exams at the end of 2009, beginning of 2010. During this summer 2009, hour build when the weather is good.
In 2010, start mod 2 and plan to do mod 2 brush up sit exams for mod 2 in winter 2010 or early 2011.
2011 do CPL and IR
Enjoy yourself and remember, if your married, make time for your family
