Agree with the others on the whole. Also, 10% of a tank tends to be taken up by substrate and decor, so you should input your tank size as ~112 litres to work out its stocking capacity. If there were a powercut or the filter were to malfunction, there is more scope for problems if a tank is heavily stocked. To clarify/extend H's point, although the stocking calculator takes into account the adult size, fish do better and grow more which is healthier for them if they are not restricted by their environment / crammed into too compact a space for them.
As for which fish to opt for, a couple of additional points that spring to mind:
* neon tetra are best suited to soft water, although their range is 18-225; however, if your water is very hard, then best not to have those;
* zebra danios are best suited to long tanks of 90cm+ for swimming length as they're active fish, whereas your tank is 81cm length.
If it were my tank, I'd probably have 8 cherry barbs, 8 rummynose tetra, a shoal/6+ cories (peppered or one of the species M suggests), but omit the neon tetras and zebra danios and feature fish (or include a mated pair or a group of the pearl gourami if space allows).
Edited to add: I was assuming you meant that your tank was still empty but has been cycling for the past 3 months, that these are your proposed fish, and that you're talking about your maintenance regime per se (eg as per for your 1st tank), rather than that you have the tank already stocked like this. In hindsight, I realise that perhaps the tank is already stocked..?
