How to connect Cisco 3750 to 2960s via fiber

We have a switch stack of 4 Catalyst 3750 switches and I will be running about 200 ft of fiber  SFP MM Duplex from one of those switches(switch A) to a brand new Cisco 2960 (switch B).   I have never done anything like this before so I am very excited and a little nervous. 

Switch B is a managable switch but I don't want to manage it, I need it to be a dummy switch to pass through data or should I manage it will that give me faster access

Switch A is an internal switch that is not hooked up to the internet.

Can someone help me with this or point me to a place I can find more information about doing this type of connection.....

The solution:
1 Connecting Fiber to another switch isn't much different then if you ran copper. They are just to different mediums. If you want to just want it to be  a dummy switch then just make sure the two ports you are connnecting are access ports on the same vlan (assuming you have multiple on the switch stack). By default all of the ports on the 2960 will be vlan 1, so change the the fiber and all of the other ports to the appropriate vlan that is on the 3750. And manage the switch. This way you can access it remotely and make any changes that come up later, instead of having to be locally at the switch.

2 You are on right track, please make sure followings;

if you are using MM fiber than USE MM module for Cisco switches
if you are using SM fiber than USE SFP module for Cisco switches

if you dont have VLAN in your network, you can ne need to do any configration on switch, but if you have you may need to assign IP on C2960G WS-C2960S-24PD-L . see below for VLAN or Etehr channel configration

For VLAN

For Etherchannels

use the correct SFP modules. Make sure that the SFP module is MM and not SM. Also, yes, if you need to manage the switch create a VLAN interface and assign an ip address on the subnet that the 3750's vlan reside on.
So:
interface vlan x
ip address x.x.x.x 255.255.255.0 (Assuming)
no shut
