I have to agree with boiler and Diver and Pip. Right now you have something that a lot of pilots wish they had: a job. Hang on to it for now.
The airlines are furloughing and I don't see much happening until 2012 or 2013, as the older guys inch closer to age 65.
What I would recommend is work out your budget, go out to the local FBO and get your Private Pilot certificate. Enjoy flying and build some time. If you've got the money, start on your instrument rating. When it looks like the airlines are coming back, then you can decide if you want to take the plunge. By that time you will be very familiar with the ins and outs of flight training and aviation.
You've got time. Enjoy your family.
As far as ATP is concerned, who knows. My gut feeling is that pilot starts are down. You might get hired as a CFI, but that one student that they're going to give you isn't going to pay the bills.
Cheers,
