I'm coming from Ruby and Ruby on Rails to Python. Where can I find or find resources about:

• The command prompt, what is python's version of 'irb'
• django, what is a good resource for installing, using, etc.
• pythoncasts... is there anything like railscats, i.e. good video tutorials
• web sites with the api
• info about what version have what and which to use.
• info and recommendations on editors, plugins and IDE's
• common gotchas for newbies and good things to know at the outset
• scaling issues, common reasons
• what is the equivalent of 'gems', i.e. components I can plug in
• what are popular plugins for django authentication and forms similar to devise and simple_form
• testing, what's available, anything similar to rspec?
• database adapters - any preferences?
• framework info - is django MVC like rails?
• OO'yness. Is everything an object that gets send messages? Different paradign?
• syntax - anything like jslint for checking for well-formed code?
