Yes there is a fantastic guide for rigging your gear.
Start out with things rigged is a very standard format... regs over right shoulder, gauges & inflator over left, sausage on left side BC pocket, light on right side etc....
then dive, dive and dive.
If things are in the right place you'll know it when it's natural for you to reach for them right where they are. If not put them where it's comfortable to reach for them for you.
Be sure your buddy knows where they are and that you have made changes.
Reading advice from experienced divers cannot confirm where your gear should go, diving can.
