After you draw the trace, in the Inspector window, next to width, click on the drop down window and select 8 or 12 mill. that will go between the pins. 8 or 12 mill is fine of data. Power should be a little heaver depending on the current. Also, in the main menu under View, set grid to 0.05" and make sure your pins line up with the grid. Draw a short 45 from the connector pin then virtually between the 2 connector pins. Sometimes the DRC will say you are too close to the pins... you are normally OK and can ignore it.
Never use auto rout and don't make 90" corners, they should be 45s. Draw all traces on 90 and 45 deg. with few minor exceptions. Don't draw ground traces... use the Ground Fill instead.
