You will need a harmonic balancer pulley puller. Autozone, Advanced, O reillys, etc will sell it to you and then let you return it if it is undamaged. They call it a "free" rental or something.
You can reinstall the balancer with the longer bolt but make sure you follow the directions fully or you WILL have issues.
As for the RTV, you can let it sit an hour or so if you want to. I never used any and had mine off 2x and never had a leak. If you want to be safe though, wait 1-2 hours after the install before starting the car to make sure it is cured.
The directions are online if you don't have a copy.
