Default deodex on for 4.3 with stock kernel

Hi guys. I just rooted my phone so i am new to this. I have root explorer and rom toolbox. My s3 is 19305t - 4.3 - kernerl is 3.0.31-2051278 dpi@dell317#1 ( I can only speak english though ).

i can tell through root explorer that my rom is not deodexed. i don't know how to deodex without risking anything. I can't seem to find a rom specifically for my 19305t on wanam's ( unless of course 19305 = 19305t as well ). Do i have the right rom finder, i.e rom toolbox? and can anyone point me in the right direction for deodexing
