Answer to Question 1:
There is no BES 3.6 for Domino. The current WC BES 2.2 SP3a is at the correct version for an upgrade to 4.0. Upgrading from 2.2.x involves significant systematic changes, and as a result you do not have a downgrade or rollback path. It would be advisable to backup all the *.nsfs in the \BES\State directory as well as the Profiles.nsf, the BBDir.nsf and all other BES specific databases (don't forget the templates BBSD.ntf, BBProfiles.ntf). This can be used as your "rollback" plan if things don't go according to plan. Or you can use these as your test dbs in a test environment, doing an in-place upgrade.
Answer to Question 1a:
You can upgrade from BES v2.2.3a -> 4.1. The choices are in-place or cut-over. If you have available hardware, install v2.2.3a on new hardware and upgrade to 4.1. Then migrate the users to to the new hardware. The BES v4.1 installation guide has the process laid out.
Answer to Question 2:
Search the forum for SQL migration or configuration database. There are numerous approaches (with the steps indentified) to migrating a local sql database to a central configuration database.
Answer to Question3:
Ping times between the BES and the mail servers should be no more than 35ms. This may not be achieved when dealing with remotes sites in some situations. Greater ping times does lead to slow mail redirection and noticeable mail delivery on part of the users.
As for the closeness of the config database, it may be suffice to say that you wouldn't want to have long connection times either.
