It appears my master switch in my 3750 stack has failed and I am replacing it today. Besides getting the IOS version up to similar code as the rest of the switches, is there anything specific I need to do to replace this unit in the stack?

Wipe the config of the new unit and place it into the stack, UNPOWERED. If you connect the switch powered into the stack you will force a re-election and you will lose the stack connectivity until it's complete.
The new switch will not be master - until you make it the master, or the other units fail.
