Proper Gear Configuration

I need some help

I am starting to get into technical diving via sidemount; I do not want to get doubles on a manifold and bands etc.

I have a backplate and wing, and a light cannister possibly from light monkey is my next purchase, I am trying to find a list that proper tels you how to setup your gear ( where to put what and attach what to where, etc)

I have 2x 40 cu ft aluminum deco bottles

1x 80 cu ft aluminum and everything else is steel 100 or 130

for cold water drysuit canadian diving

Is there an expected way, although if it makes a difference I am also left handed and in recreational diving I configure gear that is easiest for left handed divers.

Any links and/or feedback will be very much appreciated

Thank You in advanced

See you in the drink
