You forgot to mention what Mac you have. Does it meet the requirements for Snow Leopard?

Normally you would not lose anything, by default it does what we used to call an Archive & Install, to be safer do this first...
"Try Disk Utility
1. Insert the Mac OS X 10.6 Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at the top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair. Disk Utility checks and repairs the disk."

It's possible that some of your current apps may not work in Snow Leopard. You can check here: Mac OS X 10.6 Snow Leopard Application Compatibility List at http://snowleopard.wikidot.com/

Before doing anything to a computer, backup your data. You may not lose anything, but the risk is always there.
