Phone is previously rooted (I doed it after buy) and CWM Manager v3.0. Now I want to upgrade Android version to some newer, but I dont want new or custom ROM, I want to use just this official Samsung upgrade through system menu. Can I do this? Do my phone stay still rooted and still with CWM or I must root it again (or is this possible after upgrade)? What about installed apps and their settings?
Your rooted your device, so the upgrade to newer official version "through system menu" isn't possible.
Save your apps/settings with Titanium Backup, and of course make a complete backup of your system first in recovery.
Then download a stock rom (JB 4.1.2) from sammobile.com for your country. Install it with PC Odin. After that you can root it again with PhilZ kernel (search for his thread in the Development Forum).
At last you can try to restore apps from the TB backup (but I would make a clean install of all apps).
