Fixture position/Locations

As a newbie, I am trying the stage lighting with VST Live. I have purchased the three fixtures

a pair of Stage Lights Moving Head Lights

and a single Bee Eye Light UV Strobe Stage Light

Considering Stage Lighting Layout:

Should I position the Strobe stage light between the moving heads?
What’s the ideal spacing beteen them.
My wall is approximately 15 feet wide. I can place the moving heads on the floor.

Appreciate any guidance!
