If you just wipe from TWRP it only wipes you apps and data. You won't lose any media stuff so pictures, music, videos etc will stay. You should do a titanium back up if you want to restore apps and data.
If you choose format you will lose all so yes you would need to backup to either your PC or external SD. But you don't need to format to do a wipe.
