Super Simple Off-Camera Set-Up?

For someone with a 6D/430EX II who wants to just do a really easy single flash off-camera flash on a single channel and doesn't even know what Slave or Group means would the following be a good place to start and maybe even stay for awhile? I already have a nice 32" Rogue silver/white reflector.
Yes? (factoring in a lot of "off-camera" fear, but having very good results with on-camera bounce) -
