GOB,

Glad to see that you are staying put. Personally, I would be scared to use 2x6's for the floor joists, but that is just me. Also, as far as the worry about money is concerned, it is always better on a construction job to spend it up front and do the job right than to skimp and have to deal with a mess later, especially when it comes to floor joists. Replacing decking isn't too terrible, but replacing the joists after the decking is on and the roof is up isn't going to be fun.

As far as the permit goes, if one is required I would suggest getting it. However, I have seen plenty of projects done without permits. Actually, it is utterly amazing and these were all in the city. It is a judgment call on your part.
