Need to move dhcp, wins, dns to new DC and demote a DC

The primary DC is being taken out of production.  It also does DHCP, WINS & DNS.  I have 2 other servers that are secondary domain controllers and the one that is going to become the primary already has the global catalogs and FISMO roles.  I have several questions.  

1.  What do I do first?  Move the DHCP, WINS and DNS before I demote the primary DC?  I wasn't sure if it matter which order this is done.  
2.  I found some instructions for moving DHCP, but they differ somewhat.  Some articles say you have to copy registry entries, but I found a Microsoft article that doesn't mention copying the registry entries.
3.  I've done a ton of research on moving this stuff, but it conflicts so much that I wanted to see if someone does have good instructions for this.  While I support all of the servers, I haven't done much with dhcp, dns & wins.
4.  Should I do this all at one time or one by one?

Thanks - I know this is a long list.

First, if all your DC's are windows 2000 or later then they are all multimaster. Meaning, there is no 'primary' and 'secondary/backup' domain controllers. Them terms stem back from the NT days and are no longer applicable. Yes there are DC's that hold the FSMO roles, but they are just simply called the FSMO role holders.

Can you explain a little more about your enviroment?
How many computers?
Is DNS integrated?
What is your current DHCP scope like? (ip subnet, how many are in use, how many are free)

1.  Yes, you want to move all the stuff and make sure everything is working properly before removing active directory from the old DC. In fact, I would suggest keeping the DC around for a few weeks after you get the second domain controller up and going just to make sure. The order which you move DNS, DHCP and WINS doesn't really matter. Personally, I'd probably start with DNS first because that's most crucial.

2.  http://technet.microsoft.com/en-us/library/cc776587.aspx. Although, a simple network you can simply deactivate the old DHCP, enable the new DHCP scope copying over all the settings and making an exclusion list that the old DHCP server has (so the new DHCP server doesn't give out the same IP address) then once the old DHCP address have expired remove DHCP from the old DC and remove the exclusion on the new DHCP.

3.  It really depends on the environment and how complex it is.

4.  Take your time, you'll have to do these one by one.

We have 13 servers and all of them are on one domain.  I have 2/3 of the dhcp addresses on the server that I want to move and another 1/3 on another server that is also a DC.  We have one subnet with 256 potential IP addresses.
