Preliminary Conclusions

regarding which variables/parameters/effects are important and which can be safely ignored

Many of the potential variables don't affect the results: the value of q, the continuum level chosen, the wavelength range over which the fitting is done, the inclusion of the background spectrum. A few of them do, though:

Now, some of the parameters that didn't have a big effect on this particular line could be more important for other lines. We should, for example, test the effects of letting q be a free parameter for some other lines (where, maybe, the best-fit value of this parameter will differ significantly from zero). We also haven't tested it in conjunction with porosity, for example. Continuum and background could be more important for weaker lines, and these could be checked in at least one other case.
