If the kitchen has a drop ceiling remove the tiles and fill the DWV lines with water. This will expose any leaks in those. If the water lines are pressurized and leaking you should be able to see that in any exposed lines. You can use a moisture meter to detect areas of moisture on walls and floors that may be a problem. You can also rent specialty cameras that you can feed through a hole in the wall (drill one) to search for leaks and other potential problems.
Most (not all) bathroom leaks I have come across are at the shut off valve or a failed (or lacking) wax ring for the toilet. Why are you removing the sub-floor? Unless it is damaged I see no reason to do this. You can visually inspect the framing from below as well as the sub-floor. If the sub-floor is in good condition lay your CMB over it according to the manufacturer directions.
Also so you know- no drywall in bath or shower surrounds. You must use Densarmour (or similar) or CMB. Also no vapor barrier on shower or bath walls between the studs and sheathing.
You can do this project yourself just make sure you read up on and research the project. If you run into something your not sure about ask for help. Take your time and be willing to walk away when you start feeling unsure or frustrated about something. Do not put unreasonable time lines on yourself and do not work into all hours of the night. If you know someone who has experience doing similar projects or proffesional experience ask them if they would being willing to help out a little. I've helped a few friends out for dinner, a six-pack (drink after your done working), and the cost of the babysitter.
