CRJ200 CREW TURNS L WHEN THEY SHOULD HAVE TURNED R ON TXWY N AT ATL.

Narrative

I CROSSED RWY 9L AT TXWY T AS INSTRUCTED. I WAS TOLD TO HOLD SHORT OF RWY 9R AT N2 WHICH WOULD HAVE REQUIRED A R-HAND TURN; BUT I TURNED L. GND CTL GAVE US ALTERNATE TAXI INSTRUCTIONS AND IT TURNED INTO A NON-EVENT. CONTRIBUTING FACTORS INCLUDED A MAINT PROB I HAD THE FO WORKING ON SO HE WASN'T HEADS UP; AS WELL AS INSTEAD OF HAVING ASKED GND FOR A PLACE TO STOP TO WORK ALL THIS OUT I THOUGHT I COULD PRESS ON AND HANDLE THE RADIOS AS WELL AS TAXI. IT WAS BAD CRM. ALSO CONTRIBUTING IS THE ATL ARPT STILL ADJUSTING TO THE NEW RWY WHICH AFFECTS WHICH RWY WE'LL BE DEPARTING DEPENDING ON WX CONDITIONS. PERHAPS STANDARD TAXI RTES WOULD HELP EASE BOTH PLT AND CTLR WORKLOAD AND WOULD ALLOW A COMPLETE TAXI BRIEF TO BE CONDUCTED AT THE GATE INSTEAD OF A BEST GUESS OR 'WE'LL JUST SEE WHAT THEY GIVE US' ATTITUDE. ANOTHER HELP WOULD BE FOR THE ATC ARPT COMMERCIAL CHART'S DIAGRAM TO BE SPLIT ONTO 2 PAGES -- N SIDE ON ONE; S SIDE ON THE OTHER. THIS WOULD ALLEVIATE LOSING INFO IN THE FOLD AND HAVING BOTH HANDS BUSY WITH THE OTHER PERSON BUSY ANSWERING THE RADIO; WHICH IS WHAT HAPPENED IN MY CASE. ALSO HAVING IT SPLIT WOULD ALLOW FOR LARGER PRINT AND MORE DETAIL.
