That sounds right, the biggest things you want to make sure of are
1. That the new server has all the zones
2. That the new server has the same DNS role to the other servers as the old one
Other than that there really shouldn't be too much more too it - as far as moving the IP address - any time you do a swap like this you'll want to ensure that you have a qualified system administrator or your provider assisting to ensure this goes smoothly.
