Your warranty will only be void, if there is not an unroot method available for your phone.
Your phone well run faster, even if you do not use a custom Rom, if you remove the unnecessary apps. Read the forums closely, and read the root instructions three times before trying it. Also, if it is a script to root your phone, read the script. Even if you don't understand what it says, you will recognize the steps when you run it, if you read it. And it will make you feel more comfortable when you see stuff go by on the screen you recognize.
Don't unplug your phone while rooting
Don't pull your battery while rooting
Don't take your eyes off your phone while rooting, if you've never done it before (hard to get help when something goes wrong, of when asked what happened, you respond "I don't know, I was in the bathroom")
Read everything three times
