I'm not modding, I'm improving
SRP and Lime Prime are the same sort of step product. Only SRP has fillers. I would stick with LP personally as the fillers will just fall out over time and take your paint work back to it's marred self.
And to your last point, no, other way around.
Wash - clay (if you're doing it) - polish (SRP or Lime) - seal (EGP) - wax.
Ideally get a buffing towel as you will undo the work you have done with the LP if your towel is not particularly good.
