If this is a project for your work and it's your first Asterisk
deployment then definitely don't go the big bang approach in the way
you've outlined. If you do you could well be out of that job in 6
months!

The first thing I'd recommend you do is find 10 or 20 people who are
suitable as early adopters. The set up a single Asterisk server and
give the early adopters a SIP phone each thats in addition to their
normal desk phone and ask them to see how they go using the SIP phones
for calls to each other, external calls and whatever else would make
sense. Then 6 months and a lot of learning/experience/frustration
later you'll know whether to get answers to your original questions or
not.
