3750 supports maximum of 9 switches per stack. There is 3 meter stackwise cable maximum avialable in length.Check what will be the distance between the first and the last switch in your rack and then plan the stack accordingly. In gerenal practice, I have seen customer deploy a stack of 4-5 switches per stack.
You can create a stack of 6 switches and then uplink them using fiber. But why would you want to do that. The proper design would be uplinking the whole stack directly to the dtsribution/ core switches.
You go for 4500/6500 switches when you want a chassis based solution with more backplane throughput,scalability, PS redundancy, CPU redundnacy and other HA fatures.
