ON A STAR; 290 KTS FOR FUEL ECONOMY; LEVELED AT 10000 FT; WATCHING TSTMS MOVING AROUND FIELD NE TO SE TO S. ATIS CALLING FOR APCHS TO RWY 36L&R; AND RWY 27. COMPANY TRYING TO GET FLT CREWS USED TO THESE NEW COM CHARTS. ONE FLT REQUESTS OUT OF TSTMS AND OVER TO RWY 9. WE SCRAMBLE TO FIND INFO ON COMMERCIAL CHARTS FOR RWY 9. APCH CTLR GIVES US VECTOR FOR RWY 36L AND LOWER ALT. FO HAD PLANNED FOR RWY 36; THEN RWY 9 (WITH CORRECT SPD PLANNING FOR RWY 9); NOW TURN BACK FOR RWY 36 AND REALIZING WE NEED TO GET DOWN ROLLS VERT SPD WHEEL DOWN. WENT BELOW 10000 FT AT APPROX 270 KTS. I WAS CHANGING BACK TO OTHER COMMERCIAL PAGES FOR RWY 36; SCANNED GAUGES AND MADE CALL OUT TO LEVELOFF FOR 250 KTS; AND FLT PROCEEDED NORMALLY. ADDITIONAL FACTORS: OUR CREWS HAVE HEARD THAT SOME OF OUR CREWS HAVE BEEN VIOLATED FOR TRUSTING THE COMMERCIAL CHART INFO (HUGE NUMBER OF CHART ERRORS). COMPANY POLICY IS USE COMMERCIAL CHART; BACK IT UP WITH OTHER COMMERCIAL CHARTS. IF DATA IN ERROR; USE THE OTHER COMMERCIAL CHARTS. THIS TRIPLES OUR WORKLOAD! IN APCH ENVIRONMENT; NOT SMART. I WAS TRYING TO KEEP MY CREW FROM BEING VIOLATED BECAUSE OF COMMERCIAL CHARTS; AND INSTEAD MADE A MISTAKE THAT THIS CREW WOULD NORMALLY NEVER DO.
