If you dont do anything extraordinary from the steps given, then NO

For samsung phones, its a yes and no answer. From terms and conditions, rooting/flashing will void your warranty, but samsung is not strict at all, so far none is heard samsung rejecting rooted phone. but please flash stock firmware before turn in your phone for warranty

Please dont do anything else other than what it is stated there. even though rooting is not dangerous but still dont go and mess around.

FLASHING A ROM, RADIO OR KERNEL VIA DOWNLOAD MODE USING ODIN

Odin can be used to flash image files or parts of your phone. You can flash something as simple as a boot image or a complete system. Everything is packed in a tar or tar.md5 file on your PC and flashed via Odin which is a Windows OS program.

a. Make sure you have your tar file stored on your PC.

b. Reboot your phone to Download Mode [shut down your phone, then hold down the Home + Volume DOWN Buttons and press the Power Button for about 2 seconds until a Warning screen appears. Press Volume UP to continue to Download Mode.

c. Connect your phone via usb and the first box at the top under ID:COM should turn blue and have some text in it. If you are using Download Mode on your phone for the first time then you will notice drivers being installed to use it.

d. The site or page you downloaded the file from will usually give you instructions to set Odin but if not you want to load boot/recovery/system files to the PDA location and have 'Auto Reboot' and 'F.Reset Time' ticked and nothing else.

e. Click on 'Start' to start the flash. You can see what is happening in the text box in the lower left.

Kies is well known for its un-reliable.
Titanium backup - for your apps and data.
Nandroid backup - for complete whole things (app + data + phone system..etc..). You do Nandroid before flashing custom roms. If anything bad happen during flashing you can restore back to your previous set up by using your Nandroid.

mobile odin can do all that PC Odin do but from your phone, so you dont have to have a pc with you to flash all those odin stuff. get it here: http://forum.xda-developers.com/showthread.php?t=1347899

Use KIES or ODIN, both ways will un-root your phone BUT binary counter NOT increase. Meaning you only need to re-root the phone.

The best and most convenient way is to use Mobile ODIN Pro (USD 5). You need PRO because of the Ever root option. You can preserve your root and your binary counter NOT increase.

- extract the files to .tar.md5
- put the .tar.md5 into your phone
- open MobileOdin Pro.
- press Open files...
- put the .tar.md5 files
- enable/tick all three in Everroot section (enable by default)
- flash firmware
