You HAVE to have the plants as in a must in personal desire? I bet it is! 
How many watts is your tank light? Your Marineland 100 BIO Wheel filter should run WITHOUT a bio-wheel for planted tanks, because the BIO wheel gasses off CO2. For the type of fish you are going to keep, DO NOT KEEP goldfish or koi. I stress this alot because many people squeeze goldfish into a small tank and let them live short lives where as they can really live at least 10 years, 30 years even. (Don't know exact life span). Also, no piranhas, oscars, cichlids, etc.
If you plan to keep warm water fish like the majority of all the members here, you will need a heater. 25 watts is sufficient. I recommend the Visi-Therm Deluxe or the Visi-Therm Stealth. Both are made by Aquarium Systems, which is a Marineland company.
If you get low light plants and a decent amount of lighting wattage, you can get away with no CO2. Fertilizers may still be needed.
