The short, easy answers to your questions are:
Fine, No, Yes
The trail drains well, so it should be in good shape, even with the spotty thunderstorms predicted in the coming week.
There have been many discussions about bike types and tire sizes that you can check on this site (use the search on the homepage), but you should be fine with touring bikes.
Have a great trip.
