Actually, it is good to ask before leaping in and having something else to deal with.
Learning to keep plants alive is a whole other thing with much more to learn. It is smart to get the fishkeeping part down pat first. Live plants while you are learning to keep fish alive would just complicate things. You think it's hard to keep the water good for fishes, just try figuring out if your plants are dying because they need more ferts or less, more nitrate, or co2, or stronger light, or potassium, or just what. I've been studying up on plants since December, and am just now starting to get a few little plants. Plus, you will need to keep buying fertilizers, but not every week.
Learn to keep your fish alive first. Then, in a few months, when your tank is very stable and you are looking for a new challenge (read: something else to research thoroughly), then you might want to think about a planted tank.
(You at least asked some questions at the lfs before posting up. That's a start. You're always welcome to gather other opinions from experienced aquarists, just 'do your homework' first so we don't have to waste time explaining what you could find out quicker on your own. I really thought you were yanking our chain when you asked what kind of fish it was when the name of the pic told you. Anybody here is glad to answer an honest question from someone who has truly made an effort to find out something about it him/herself.)
