Yes, use pry and pry-debugger. Visit http://pryrepl.org/ for more info.

I like the Rubymine debugger. Rubymine is a paid Rails IDE.

Yes.

Assuming you've started rails with:

rails s --debugger

and got a line in your code:

debugger

then, when you hit that breakpoint, just press: 

Enter

to step through code line-by-line. You will also see Ruby code being executed en route as your app is being parsed. Not sure how you switch that off.

Of course you can. All you have to do is install Netbeans 6.9. It has a fastdebugger inbuilt in it. You should start the server in Debug mode. You can then set breakpoints in your code and step and inspect line by line.
