You can't get them back
Once its gone its gone.
To retrieve deleted iPhone applications, click on "App Store," then click on "Updates" (even if you don't have any updates). Click on "Purchased," then click on "Not On This iPhone." It will give you a list of every app you have purchased that is not on your phone.
No... you can't retrieve bookmarks
If the song is deleted, then you can't put it on your iPod.
Yes, as long as you have ever used the iTunes to sync files to your iPod Touch, even if the device is lost or you accidentally deleted or wiped out the data, you still have chances to recover those precious deleted files. If you have made backups on iTunes or iCloud, you could use a third-party tool like PhoneRescue to get back your deleted songs on your iPod touch. For no backup, you can still use the tool to retrieve songs directly from device.
