Going down your list: I'd strongly suggest to get a whole liquid test kit, not only pH. You'll over time need to measure your pH & KH regularly, specially in the begging. For cycling and afterward to ensure fish health, you'll need to measure: Ammonia, NO2, NO3
Ram's I'd def not recommend for anything smaller then a 20g.
Neon's are school fish and ideally kept in groups of 8, rather 10's; the very same apply's to the cory's housing only 3 will make them feel extremely insecure, which will stress them out, permanent stress in fish just like for us will cause early death.
Oto's are EXTREMELY sensible fish and should absolutely not go into a newly cycled tank. Let the tank establish for several months before you add them, otherwise you're pretty much guaranteed to loose them.
Some of the fish you've chosen require to have soft acid water, unless you can test your water and see what you have, I'd bee a fool to tell you to get these fish for your tank.
I'm not saying any of this to upset yu, but I don't want for you to run into the wrong direction, loose fish, get upset and quit the hobby again
2 Swords sound good for starters, but I'd add many many more then that to a 13g. Maybe something like Vallis, various Cryptocoryne, Ludwigia, Hygrophilia....Look throught my tanks under my name to the left under "Aquariums" you'll find a variety of plants within these tanks, maybe you'll see a set up you like too.
