For the FTDI take a look in the Sparkfun library
and grab the M06 part. There might be a specific header somewhere if you feel like scouring the web.
With regards to the resistors, when you are looking through the 'resistor' library the parts have a 'type'. The First half is the width in mm (at least for the EU parts) and the second part is the length. The 'grid' is the distance between the two solder holes.
For example, a 0309/10 resistor is 3mm in diameter, with a 9mm length and the holes are set 10mm apart. Therefore, simply measure your resistor and use something similar.
