sql server replication : how to replicate schema changes

Hi all,
I have a large db that I'm going to set up relication to replicate to a
different server. it's about 300 tables and a lot of tables with milion
milion rows of data. This is a vendor's db and the schema is going to be
changed very week through SQL scripts.

Questions:

1. what is the best and most efficient way to create an initial replication?

2. Can db backup and restore being used to save time of loading data?

3. what is the best way to handle weekly schema changes without reloading
data? and how?

Thanks,

1) SQL DMO is an option as you can iterate each table with a pk and publish
it.
2) yes, but you have to do a lot of work to get this working in SQL 2000. In
SQL 2005 do an initialize with backup.
3) log shipping. With SQL 2005 you can replicate ddl. With SQL 2000 use
sp_repladdcolumn or sp_repldropcolumn for schema changes. With many schema
changes log shipping makes a lot of sense.

Tom,
for (1) and (2) you can consider a nosync initialization:

For (3) many changes can be done using sp_repladdcolumn and
sp_repldropcolumn. For more complicated changes please look at
