If by 'élite' you mean the élite company usually wearing busbies (colpacks) instead of shakos, as the 1st company of the 1st squadron they were placed on the first place right side when the squadron was formed into line. When the squadron was formed into column (colonne) the élite company would take the lead.
They were never mixed with the others because they were formed into a seperate company. Hope that helps.
If you are looking for more detailed reference of how company and squadron formations looked like you might have a look at the diagrams on page 29 in:
Bukhari, Emir: Napoleon's Line Chasseurs, London: Osprey 1977 (Men-at-Arms; [68])
There, positions of all the officers, NCOs, trumpeters and rankers are given.
