More than likely yesWould taking out all my sand(due to going B.B.) and rock to rescape cause my tank to cycle again?

How long will the rock be outside?
Will they be dried by the time you put them back in?
You can slowly remove sand over time depending on how much you have in the tank and how long it's been in there. To re scape the rocks it should be fine to pull them out for a few minutes or so but keep in mind you should place them back the same side up because the beneficial bacteria on the surface of the rock.
If your avatar is an accurate representation of the tank currently, that's what I would do. Don't sweat it. I've sucked out sand with a hose and there's minimal(if any) disturbance.
Also don't need to get every grain out. When you get most of it already, you can come back to it on the next and the next and the next water change.
If you decide to put sand back into the tank in the future, that's more challenging and time consuming.
