Only if the Time Capsule has a fiberoptic/DSL modem built into it.

No.
Do I have other options? Stand alone modem? Switch to a different provider? I have no emotional attachment to AT&T.
You could switch to cable Internet with your local cable TV provider. Then buy your own modem (like the Moto SB6141 for example) to avoid the modem rental fee with them. Then add the Time Capsule to the mix for your router/backups.
Looks like this will solve my issues. Will this modem be faster than my uWire, or does it not matter?
