I saw two identical threads, so I have merged them. This way we will all be seeing the same issues and suggestions, which will allow for a better informed response from everyone.
On the cycling, with live plants you won't have a "cycle" that is discernable. Plants are so efficient at grabbing ammonium (ammonia) they out-comppete most of the bacteria, and with plants you don't have the nitrite/nitrate stage. Once the tank is planted, you can add the tetra with no worries.
On the rams, I would suggest waiting until you find some in the store, and observe how they interact in the store tank. If they are not juveniles, some of the male/female characteristics noted in our profile will be noticeable, plus the male's tolerance of females and intolerance of other males strictly in their behaviours will be obvious. Just a thought.
I would get a decent tube for the light, as I mentioned previously. Plants will not start off well with poor light. Light drives photosynthesis, and that is how plants grow. Algae though is always waiting to take advantage, and being able to use any light and especially in a new tank that is unstable in water for a while, this can be problematic.
