Time Capsule and FiOS

Hi, I own a Time Capsule (which after 18 months is still working fine - knock on wood). I am considering switching my Internet service to Verizon FIOS. The Verizon rep told I would probably receive an Actiontec modem/router, but I could disable the router function and continue to use the router function of the Time Capsule. If anyone here has a similar setup, would you be able to answer these questions for me?

1. Is Verizon right - will my Time Capsule work with FIOS?

2. The Time Capsule is n and I think the Actiontec is g - is that going to limit my speed? (I was hoping the opposite would be true.) I am probably signing up for the FIOS 25/25 plan.

3. There's a USB port on the Actiontec modem but I haven't found confirmation about attaching a hard drive. If I ever stopped using the Time Capsule and decided to use the router function of the Actiontec modem, could I attach a hard drive for Time Machine backups?

4. I also plan to buy the Sonos ZonePlayer wireless music system and would have to connect to one of the Ethernet ports on my router a Sonos "bridge" device - if I continue to use the Time Capsule as the router will I still be to be able to attach other devices to it?

Thanks in advance.

 

Thanks - Just curious, what were your Sonos problems?
