krenshaw, will this be your first all-grain batch?
Yes, the mash is 152°F for 60 minutes. The mash out is optional, but it will help the wort to run off faster, especially with the high % of wheat used. If you can heat your mash-tun directly then you can heat it while stirring to get up to 165-168°F, then let it rest 10 minutes before sparging. Then you would sparge with the 165°F water. If you can't apply direct heat to your mash tun (e.g. if you mash in a cooler), then you will probably be fine just skipping the mash out, and sparging with 165°F water.
