Leaving aside the "exchange really shouldn't be on a DC" issue......
1) You need to transfer FSMO roles from the old DC to the new DC: How to view and transfer FSMO roles in Windows Server 2003
2) If the old DC is broken to the point that's not possible, you need to seize the roles: Using Ntdsutil.exe to transfer or seize FSMO roles to a domain controller
3) You should also check your secondary DC is working properly using dcdiag, repadmin and netdiag - don't nuke the original DC until you're sure.
4) I'd also back up D: (yes, even though you don't plan to touch it).
5) You can back up the share info - it's held in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\lanmanserver\Shares - more info Saving and restoring existing Windows shares

You need to make sure that you have transfered the FSMO master roles over to the new DC as there are certain core bits of AD that only run on one DC at a time.

You are right about the shares needing to be remapped. You could also have issues with exchange if you are keeping the same server name because it stores lots of stuff in AD which may need to be cleaned out prior to installing again.

Exchange should remember the organisation settings but it would be a good idea to copy them down in case. Depending on the restore method you may or may not have to reconnect each mailbox to each AD account but I am unsure on this.

I had forgotten about transferring the FSMO roles. Will I also need to make the new DC a global catalogue server too?
Exchange is in good shape.
Thanks for the tip for saving all the share info.

DHCP doesnt replicate, infact you dont have it installed on more than 1 PC (well you can but i wont go into that). You can however export and import all the settings and reservations.
