new to rooting

[sync-a-cide]

I'm new here and have some pretty simple questions as I become more comfortable with android and the possibility of rooting and ROMs. This does void your warranty, correct? I have sprints $7 a month insurance, does it void this too? should i cancel it? Is there anyway around it, like re installing back to factory settings if i need to? Can you root and and use the same ROM, but just have root access?
