I looked over it quickly and the one thing that stood out to me is the number of fish you want in total. Something like 45? thats an awful lot of bio load for even a 55. Even though they are small fish. especially if you're only going to be able to afford basic filtration. I think you're better off sticking with larger packs, but fewer types.
10-12 (another school of something)
5-6 cory cats
and a small group of dwarf cichlids (almost all will live peacefully with all of your tetra ideas)
this would easily be fully stocked.
on your list you have 6 or 7 different types of tetras, they won't all school together and you'll end up with traffic jams in the middle of the tank. if won't look very organized. in my 40 gallon I have a group of 13 neons and to me its far more attractive/impressive than 3 different, smaller groups of tetras.
planted tanks tend to be about the entire scene, with fish acting only as compliments to the layout of plants, rocks, driftwood, etc. stuffing it with fish tends to detract from the overall look of a planted tank.
but definitely do what you want for fish stocking and over time you'll learn what looks more appealing to you. just my quick two cents.
