ok.first off well welcome to the site!
For a cannister filter for that tank I would personally go with a XP1. you can pick them up for about 70 bucks off petsmart.com or DRfostersmith.com or even big als online.
depending on your setup you can do a few different things with lighting. but for sake of keeping things simply I will reccomend to you looking into the Coralife Freshwater Aqualamps. IMO they are the best priced quality fixtures. and come with the proper spectrum bulbs.
You could go with the Jebo or oddysea fixtures you will find on Ebay. But quality is not really there. and you could wind up with alot of problems (burnt down house) So I would say stay away from the cheap extremes.
For CO2 you have a few diff options. You can get everything you need by contacting forum member Rex Grigg. www.rexgrigg.com
He not only sells all the stuff you need there are some great articles there that put alot of this stuff in laymans terms that will help you understand not only what you need but why. I highly suggest giving it a view.
You will have more questions. we all do. But this will get you some of the basics covered. .
The drfostersmith site also has some decent CO2 system packages for fair price.
then we can talk about ferts.
