I work in a multi domain plant.
Statement 1 is true.  You can opnly have 1 PDC per domain.
 
Statement 2 is true and false.  If you have 2 domains and 2 PDCs and are 
trying to go to 1 domain you will need to rebuild one of the PDCs and make a 
BDC when you install NT
BUT
If you have a single domain with 1 PDC and multiple BDCs then you can demote 
the PDC at anytime by promoting one of the BDCs. (Just did this a month ago) 
You can then prepromote the origainal PDC, which is now a BDC to be PDC 
again (Did this yesterday).  You could also promote a different BDC to be a 
PDC.
However you say you cant demote a PDC yt you can promote a BDC.  How would you 
get the original PDC back into the network unless you could demote the 
promoted PDC.

SO yes a PDC can become a BDC and vice-versa.

You can NOT promote a server to be a BDC or a PDC.  The SAM is not stored on a 
server.  You would have to re-install NT on a server to make it a BDC.
This goes the other way as well you can NOT demote a PDC or BDC to be a server 
without re-installing NT

All these concepts are taught in basic Mic. NT courses.
The key to it all is that only one PDC may exist per domain.
There can be as many domains as you want
You can set up trusts between these domains.
There can be as many BDCs in a domain as you want.
There can be as many servers in a domain as you want
There can be as many workstations in a domain as you want.
Any BDC may be promoted to PDC thereby demoting the current PDC to BDC
Servers will remain servers unless rebuilt.

The PDC MUST be the first computer installed.
You can not create a BDC unless there is a domain to put it in.
Same goes for servers and workstations.
