Will Canon 600D be able to do these?
The question reads like: how I get the best quality out of a given setup/financial scale. just keep in mind, that you get what you pay for - so don't expect fancy 4K-movies out of this ;)

The first two things I would suggest to buy are microphone and tripod. Why? If you want to do a silent film, you can use the internal mic - otherwise I would strongly suggest to use an external one, because the internal one might catch too much noise during quality and characteristics.

holding the camera with your bare hands can always cause movements within the movie, so a cheap tripod is better than none. if you buy one, just keep in mind that you might move it during the shot, so it should be moved smoothly. 
also don't forget that Autofocus (as used in a DSLR) might not work during filming, so you've to pull the focus.

I would strongly oppose to use a certain lens for a certain style of picture - just try to get the best quality out of the setup and add the "style" in post processing. if you have motivation, passion or the faith not to change something of the style in post processing, than you might buy a lens/filter to archive this.

if you consider buying a Canon EOS, you might have a look at magic lantern for an alternative firmware with an movie making aspect.
