DATA3 is just a data connection between the FT2232 and the FPGA. The FPGA can be configured to use it as a DEV_CLR signal, which is basically a reset, without actually having a reset in your top-level design entity. Personally, I'd configure the pin to be a general purpose I/O and treat it as an external reset control in the design.

One of the thing I am not clear about, is how to use the ftdi command ft_setbitmode.

Set bitmode is used to change between MPSSE and regular modes.
Check out the attached programmer for the Morph-IC.
