on a quick look,

> Connect VCC direct to pin 40..
> what sensors??
> The reset circuit ! - add a switch.

well -if it suits for micromouse or not - its all about your algo and machine.

but is it necessary to use a switch in reset circuit???

also I will be using the ready made available sensor circuit.

and are those zener diodes used for the protection purpose across the stepper motor connected alright? :?: :?:
