For a single T-1, you want either a T100P or a TE110P, whichever Digium 
is shipping now. You want your T-1 configured as an ISDN PRI using NI-2 
signaling, with the T-1 loop in ESF framing and B8ZS line coding.

As far as configuring the DIDs in Asterisk, you will need to learn the 
Asterisk dialplan system (extensions.conf). The wiki contains lots of 
information about that, so you should start there and come back here 
when you can ask more specific questions :-)
