Monitor your NH3/NO2/NO3 cycle. Just with the LR (no fish needed) watch for the spike and drops to 0.0, after then can slowly start adding. If too much too soon can cause anyother cycle.
Found when I setup my 75g took about 3 weeks.
Pumps, depends what type of tank you're going for, could be lots already. Also to consider the added flow once you add your sump.
