Holy smokes, Neil (@Flyer) - you do have a lot on your plate. It sounds like finances and planning for retirement are quite understandably a driving force right now, and it may well be that taking the Big 4 job is the right choice for you right now. If you do take them up on their offer, will there be a long-term contract involved? Do you get the sense that the company needs an answer from you right away, given that you had such a casual meet and greet with little discussion of actual job function? How much leeway do you have to marshal your forces before you need to decide one way or the other?
