Your choice, but I keep them all. Conversion is never perfect, and I never know what format will work best for me. Storage is cheap.

Tip: when using the tag browser to select multiple tags hold down the shift or ctrl while selecting tags. This allows you to select multiple tags.

I have a disk of source files that I never delete. I move a well formatted version of the book I want to add to calibre then convert to epub. Once I have a final version of an ePub suitable and edited for my device(s) I remove any other version from calibre. This is my preference, to keep my library as small as possible because I use Dropbox and thus limited space. I currently have about 1600 books and they take up about 1 gig of drive space.

Many folks keep 1 copy of every format they have in calibre. Either way most of us keep original source files as backup.
