keep the lights low and save for all your equipment
lots of members on here dont have a dual stage reg and never have a problem with eotd, that doesnt mean it wont happen though and a dual stage is peace of mind. i would start with flow, cheap powerheads can be very good at distributing co2 and nutrients, my mate used to use one like you have in your tank with a diy spraybar, worked very well but just a little ugly(will soon be hidden by the jungle)
personally I would hold off on buying too many plants until you have all the equipment you need. now is a good time to start an emersed nursery on your window cill to rapidly increase your plant mass( theres a link in my signature that will show you how to get started and I'm sure members will send you a few cuttings to get you going) all this can be done while saving for your equipment.
I know you want a beautiful tank full of healthy plants but ramming a load of expensive plants into a tank without all the right equipment is just a waste of money imo.
once again patients we've all been there and many of us have wasted a fortune buying plants then killing them
and good look
