If your only running the phone on the port, there is no need for GigE to 
the phone, and many phones only support 100Mbit.

If your running phones with built in switches, a computer off the phone, 
and the phone supports GigE, the GigE will help keep the computer from 
overloading the total available bandwidth, but that is a very low chance 
of being an issue to start with.

GigE all ports vs GigE for your server, and 100Mbit for your phones 
really is not a major difference, but the price difference between the 
two is also very small now days, and you are buying equipment with a 
reasonable service life (3-8 years in my opinion), so it's a balance 
between a few extra $ now, or waiting and seeing if you want it in the 
future, and paying some amount of money to swap it out.

Most of the deployments I have done are with 100Mbit POE to the phones, 
and GigE for uplinks between switches and to the Asterisk server(s)
