The app part, transfer purchases to iTunes http://support.apple.com/kb/HT1848
The notes part, on the iOS device go to Settings > iCloud > Notes > Toggle On. In the Notes app tap the button in the top left corner until you are on the Accounts page and select iCloud.
On the Mac go to Apple menu > System Preferences > iCloud > Notes > Toggle On. In the Notes app select iCloud on the left.
At some point you will be prompted to create an iCloud email.
Any notes created in the iCloud folder(s) will be pushed to your other devices. If you have existing notes you will need to copy and paste them to this folder.
Hope that helps.
