The WIC-1DSU-T1 is the acual WIC module with a single T1 RJ45 type physical connection.
The Daughter card, best I can tell, is a little circuit board with no physical T1 interfaces that attaches to something else, like a WIC module.
Where are you getting these part numbers, and in what context?
This document shows a picture (Figure 2) of a VWIC-2MFT with optional daughter card for echo cancellation


the part numbers were gotten from
sh diag

the T1 (2 port) Multi-Flex Trunk WAN has 2 T1 interfaces.  

I was wondering what thier functional differances are and how they differ in terms of config.

So, you have a WIC-1DSU-T1 and you also have a VWIC-2MFT-T1 module?
The WIC-1DSU-T1 module shows up in the config as a Serial interface and uses service-module commands. Example:

interface Serial 0/0
 service-module t1 timeslots 1-12
 service-module t1 clock source internal

The VWIC Multiflex trunk shows up first as a controller and you configure the controller with channel groups to create serial interfaces:

controller t1 0/0
 channel-group 0 timeslots 1-24
controller t1 0/1
 channel-group 0 timeslots 1-24
 clock source internal

These matching serial interfaces are created by the channel-group commands and they do not further use the service-module commands.

interface serial 0/0:0

interface serial 0/1:0
