Hi Pariah87, welcome to Fishlore.
Glad you joined before starting things up. I was lucky to experience the same so I avoided some mistakes others made (like adding fish without cycling). I believe your stocking plans are doable, well balanced and not exceeding the tank capacity. As for using or not plants from the start, I strongly suggest you go planted, say with low light, hardy, easy to care for plants such as Anubias barteri varieties.
Please read around about the
nitrogen cycle and fishless cycle. If you cycle your tank fishless, say with
ammonia solution, you would be able to add most of your
bio-load at once. It may feel like a chemistry lesson but you'll get familiar with the terms. I had to read that info several times to grasp the concepts behind this biological process that allows our aquariums to be healthy.
Given that some fish are somewhat sensitive to newly set aquarium water parameters variations, I would consider placing the Guppies and the Bristlenose pleco first. If still you are into Black Neons I would wait at least four weeks (two for other hardiest tetras) after testing water parameters so that I feel sure Ammonia and Nitrites remain steadily at zero and
pH is stable (stability is by far more important than the actual value, given it is within 6.0 - 8.0 for most fish in the trade).
Freshwater Shrimps are, in my opinion, the most sensitive in your stocking options. Please consider the opinions of those with more experience than me. I don't have (don't intend to) keep Plecos so there might be more accurate information than what I know (I believe they are quite hardy). I do keep Black Neons, Guppies, and
FW Shrimps.
