Term::ReadLine by itself only provides very basic functionality, mostly stubs for functions that are actually provided by other packages, namely Term::ReadLine::Gnu, Term::ReadLine::Perl and others. But you do not use these modules directly. You always use Term::ReadLine, and it detects which ones are installed and picks the best one (for some definition of "best"). There is a minimum set of supported methods, and you can check what other features you have available through the Features method.

As for history, if you have Term::ReadLine::Gnu, it is enabled automatically and you can access it using ctrl-p/uparrow and ctrl-n/downarrow. You can also manually add lines or otherwise manipulate the history. See the documentation for Term::ReadLine::Gnu for details.

I have never used tab completion, but there are a number of functions that deal with that in the documentation, so you should be able to figure it out.
