Switching ISP to Comcast

We are switching from at&t to Comcast ISP.  When we switch what to I need to keep in mind?  What pitfalls should I be aware of?.  

The basics
We host our own website
Our domains are registered though a separate service (not through our ISP)
All traffic comes in to a router then a Firewall then to our network
Email filtering is hosted by a separate service, we use exchange 2010 once we receive it

Thank you in advance

Make sure they help you port your IP addresses, especially if you don't own them outright.  Aside from that, it should be straightforward.
