Plants are actually a lot easier than most people think. My favorite floater as well as java fern don't need ferts (stem plants do for good growth). All you need to make sure you have is the right light (which can be found at Petco) and a timer for said light (really helps to prevent algae).
If you want to fertilize, it's really easy to do and explain. For the basic plants that I'm describing you need one liquid fert. Seachem Comprehensive is what I use. You only need to worry about root tabs and other specialty ferts if you get sensitive plants. So once a week about 24 hours after a water change, squirt some in the tank.
I actually no longer gravel vac my tanks with plants. The fish poop is great plant fertilizer. That way I also don't have to worry about disturbing the roots.
Really, basic plants are quite easy. It's when you get into high lighting/CO2 situations that things get more difficult. But that is also the kind of stuff needed to create those beautiful aquascapes you see online.
