Who are the "people"

Duhh..you want to install CWM or you want to flash custom kernel..!??
Anyway..for  .tar files..you can use MobileOdin
For flashable zip files you need to use CWM.
And for those two files..it must be for your LTE version and not the international GT-I9300 version. Otherwise you may bricked your phone 

If the CWM comes with  .tar files then yes..you can flash it via MobileOdin. Btw..where did you got that CWM files.? I believe it comes with instruction on how to flash it correctly. Just follow each steps and you'll be fine

Duhh..why so scared..? 
From the images it seems that your MobikeOdin correctly detect the CWM  .tar files into its recovery section. All you had to do is flash it then wait for reboot..that's all.
It just as important that the files was meant for LTE CWM recovery.

You still don't have CWM..how to do backup.
But do your apps backup via Titanium first.

All contacts you can sync again with GMail account. For apps..that's why I said..backup it first by using Titanium Backup app.
Wipe or not wipe doesn't matter. Sometimes your phone goes boot loop then your final solution is to factory reset. You still lose all your contacts and apps. But flashing kernel seldom wipe the phone
