Not with the iPhone.
If you select Sync Music under the Music tab for your iPhone sync preferences with iTunes followed by a sync, all music and probably any other iTunes content will be erased from your iPhone when doing so, and a warning message should be provided indicating this will occur.
iTunes includes an option to transfer iTunes content that was purchased/downloaded from the iTunes store (including 3rd party apps) from an iPod or iPhone, but this is for iTunes content that was purchased/downloaded from the iTunes store only. Re-authorize your computer with your iTunes account with iTunes if you haven't already done so. With your iPhone connected and without syncing, at the iTunes menu bar go to File and select Transfer Purchases From - the name of your iPhone.
If a 3rd party app does not transfer to your iTunes library on your computer, you can re-download the app with iTunes and you won't be charged again for a purchased app as long as you use the same iTunes account to re-download the app that was used to purchase the app originally.
There are also some 3rd party paid utilities that provide for transferring iTunes content that was not purchased/downloaded from the iTunes store (music imported into your iTunes library from a music CD that was transferred to your iPhone), and for any photos that were transferred from your computer to your iPhone. Photos transferred from your computer are optimized for viewing on your iPhone - the original resolution of these photos is reduced in the process, so when transferring these photos in the opposite direction, the original resolution of these photos will be lost in the process.
If selecting sync music under the Music tab for your iPhone sync preferences with iTunes followed by a sync does not remove all music from your iPhone along with all other iTunes content (and it should), you can restore your iPhone with iTunes.
