The ethernet interface on the router will get an IP address (presumably
from your ISP) and that will be the default gateway for the other hosts
on that network.  Yep, just plug them into the switch at each site and
you're ready to rock.

Usually if a business buys a T-1, the ISP will help in sourcing the
right equipment and getting it configured.  They will also be your first
contact if it goes down, and most will handle dealing with the telco on
your behalf.  It's simply not feasible today for an ISP to expect a T-1
customer to know about things like DLCI's and B8ZS (grunt grunt!)

Frame-relay, Point-to-point, and T-1/E-1 are all possibly related to
what you're doing.
