Your catfish are Corydoras, aka Cories.
Well, the green one looks like a Brochis splendens, but they are called Emerald Cories and closely related to cories. The spotted could be any number of the spotted cory species.
They are shoaling fish, meaning they like to have company, preferably 6+ of their own species. For now, since the tank is new, I'd wait on adding anymore fish to the tank.
Regarding the plants, its actually good to cycle with plants, especially if you have fish in the tank. I'd pick up
a lot of Anacharis, as it will take in some ammonia. Also, if you can find some Hornwort, get some of that too. You will be very limited with stock lighting, as far as plant choices go, but any plants will help. The 2 I mentioned are fast growers that take in nutrients faster than others, so it really helps when cycling with fish. You could also get some Cryptocorynes, Anubias, and Java fern, but these are slow growing. Try to get a lot of Anacharis if you can, as its good in low light and good for a cycling tank.
When fishless cycling, plants really aren't necessary and can actually be harmed by the high levels of ammonia (or so I've read), so its best to fishless cycle without plants, but when you are cycling with fish....pack in the plants! Just make sure you choose plants that will live in your lighting.
Cycling will take 4-6 weeks, so be prepared for alot of water testing and water changes. Hopefully all the fish will make it. That's quite a fish load to begin with IMO and I would have skipped the Cories, since they are pretty sensitive to ammonia and nitrItes (more so than others). Feed every other day during the cycle and check your water daily for ammonia and nitrite. DO NOT add anymore fish to the tank until your ammonia and nitrite test 0 and you have measurable nitrates.
Test strips are inaccurate and I really don't like the ones that don't give numbers (not sure if thats what you have). You have no idea what they consider "dangerous" or safe, so they aren't good for cycling IMO....especially with fish. I'd suggest getting the Aquarium Pharmaceuticals master test kit. Liquid is the way to go. You can print out this:
