64-but is getting there
Several if my apps use it. Edovia Screens, Twitteriffic, iWork, iLife, DJay and tons if games. I'm surprised by the uptick in developer adoption this short into the A7 life cycle
iOS is based on OSX originally. The two have a lot of commonality so not entirely sure what you are asking.
Are you asking if 64-bit means iOS will be more like Mac OS?
- if so we are there pretty much. There is a lot of shared things between the two
Are you asking if 64-bit means "Windowed" based GUI?
- if so, I wouldn't hold my breath. We will probably get more multitasking features designed around touch interactions but that's probably it

As the others said, not yet, same as 64 bit wasn't a huge deal on the first PM G5 other than addressing RAM. But it lays the groundwork for the future. You gotta start somewhere, right. Apple needed to do the move now because tablets are slowing eating away at laptops. Apple is preparing itself for the day when OS X and iOS merge. But in the meantime, if Apple is going to put a 64bit proc in it might as well get some mileage out of it. I wouldn't upgrade because its 64 bit but there are plenty of good reasons in addition to the A7 to buy the Air or new rMini.
Don't know if I agree about the OS merge. Maybe 5 years past but I see Apple really focusing on making great tablets for what they do and great notebooks for what they do best. Apple likes to stay focused on the best solution to the problem. Windows 8 is a perfect example of having no restraint or focus.
