How to connect CISCO 3750 thru Stack cable

[ZAHIDHASEEB]

1- Currently we have two switches with same IOS. Do we only require to connect both switches physically thru stack cable ? or we need to configure both switches too on IOS ? 

2- Do both switches work as a single logical switch and load will be distributed if we connect all hosts machines to both switches with a 50/50 ratio ?

Thats good you identified the Physical issue fixed.

its not common when  2 switch in stack we expect to 1 and 2 ( to be honest your config shows 3 and 4) , this not cause any issue,
