How To Stop Using WHM/Cpanel

I have my own server which I use for my own websites.

I use the following features of WHM -

Creating accounts
Deleting accounts
Creating "packages" for my accounts
Restarting services
...and possibly one or two other items once or twice a year.

I use the following features in Cpanel -

Checking statistics
Adding e-mail accounts
...and possibly one or two other items once or twice a year.

I'd like to break the (small) WHM/Cpanel habit I have and do all of the above via the command line.

Is this a big task?

Where should I start?
