Archive files, backup, buy a larger hard drive.... you have an iMac? this is not the forum so maybe a hard drive isn't as easy.
It depends. Not that you can't but why.
What does matter: keep at least 10% free, 20% better, and more like 40% free.
move media files
move the iPhoto Library to external but fast disk drive, esp. if you have new Thunderbolt storage interface.
move the entire itunes media in same way.
But whatever you do make sure to have one or more backups of what you delete.
Even web browsers can create GBs of cache, temp, history and such. so can logs and printer temp files.

Most space may be taken by video, music and images. Perhaps some of these could go elsewhere. Make sure everything is stored in at least 2 places. Disks and media can fail at any time without warning.
I don't subscribe to keeping a particular percentage of hard disks free but I like to try and keep free about 0.5 GB plus 1.5 times RAM size (more critical for portables than desktops) - a total of 2.75 GB in my case. You may need more for particular processes or applications.

As an aid in your situation, download from the Internet OmniDiskSweeper (free) and open it. It will show all of your files and the respective sizes. This should help you to determine what to delete and/or transfer.
