Does a full simulation need to be done with flexible tooth first to get the perturbation information for generating Fast file ? or can we always do a rough perturbation and generate a Fast file ?

the full simulation does not need to be done but it is recommended to ensure that a gear pair operates within predefined range of workspace dimensions - inspect normalized displacements of gears as explained in the Gear AT Fast Modeling tutorial (STEP 8) accessible from FAST testrig dialog box. That means the normalized relative displacements should be in range of <-1.0, +1.0> or not far beyond. Note it is linearly extrapolated beyond the range.
It is also not meaningful to overshoot perturbation by high factor thus operate at very low values of normalized displacements since it would mean the interpolated values are more-less constant, especially having precomputed very few perturbation steps.
Note that default "Torque (TZ)" = 2000 Nm value is very high for majority of applications.
