It depends on how you set them up, and what apps are on them.
In Settings > iTunes & App Store you can turn on Movies, Apps, Books, and Updates. The first three will cause your device to automatically download anything you purchase or download on the other device or in iTunes on the computer. This only works for content purchased/downloaded from one of Apples stores. It won't work with side loaded content.
Updates automatically downloads updates for the apps you already have on the iPad.
Almost all of the native apps will stay synced, provided you have iCloud turned on for those apps on both devices. (Settings > iCloud)
Mail depends on what kind of email service your provider uses. IMAP and Exchange will stay synced. POP3 won't; at least not very well.
All other apps depend on the developer, whether they provide syncing, the method they use, and whether you've set it up.
If you use iTunes on a computer to sync, then you need to have the content you want to sync on the computer. If you want non-iTunes Store content to sync, you need to import it to iTunes. (and iBooks if you have a Mac) Each device will sync what you set up in the tab for that content. It can be different or the same. iTunes remembers your settings for each iPad it syncs.
The best way to tell what iTunes will/won't sync is to go through the tabs and play with the settings. You can always choose 'revert' before tapping 'apply' or 'sync' so that you don't mess things up.
