It is safe except it is tethered jailbreak which means if you try to reboot your device or the battery dies you will have to plug it into your computer and use RedsnOw to be rebooted. Go to YouTube and look up redsnOw 4.3.5 jailbreak which will show you how to do it.
For 3.1.3 i recommend going to redsnow and downloading the latest version. then go and find a download for 3.1.3 firmware and follow the instructions on redsnow
Just go to Google and type in: redsnow 0.9.5 beta 5 download for Windows Tons of stuff will come up with download links.
yes it is you can use redsnow to do it

Search Google for RedSn0w or Green P0ison, there should be a few websites :)
i am guessing you are trying to jailbreak your device. it can all depend upon each device but it shouldn't take to long. My suggestion, if possible don't jailbreak with redsnow, try jailbreaking with greenpois0n or limera1n. hope this helps :)
