Not trying to discredit Aquarium Driftwood at all, but you may want to consider buying your plants from a separate source. For driftwood they will probably be your best bet though.

Also you might want to figure out what kind of tank you want before ordering. By this I mean how much lighting, fertilizing, pruning, CO2 requirements, water changes, etc. you are willing to have. Generally, lower light tanks have fewer requirements.
I suggest doing some research, finding plants you like and ordering those. Try to start to easy to moderate plants, not difficult ones. Also LOTS of stem plants from the beginning is a good idea.
