Welcome to The Planted Tank:
First off, the specific care of each of your plants depends entirely upon the species, because there are both tropical and temperate sundews and pitchers. Depending upon their area of origination, some carnivorous plants actually tend to do poorly in captivity.
It sounds like you are off to a good start, but there are a few things that you should consider:
-First, what wattage is your light? For most of the pitcher and sundew species, you really need around 30w (or more, for best colour,) of light over the vivarium.
-Unfortunately,
Dionaea are actually a temperate plant, which means that they need to go through a process of diminishing light and temperature to initiate hibernation. Unfortunately, this makes them rather notoriously difficult to maintain in captivity, as without this "rest," these plants only tend to live 2 or 3 years.
-It's sometimes difficult to maintain several species of carnivorous plants together, because of their varying requirements for humidity, light level, soil preference, and water uptake; however, don't let this distress you too much:
Quite a few tropical species of nepenthese, utricularia, drosera, and pingicula (not to mention some more exotic genuses,) grow quite successfully in vivaria. With a little tweaking of the environment (hardscape to provide some plants with shade, etc,) strategic manipulation of the soil (for drainage and acidity, depending upon the plant,) and some other planning, you can have a beautiful mixed community.
I really advise that you visit:
http://www.cobraplant.com/caresheets.html for basic information on many species of carnivorous plants. It'd also be a great idea to see if you can find forums specifically catered to carnivorous plants, and find what processes they follow to successfully maintain these rather unique environments (as it's been a couple of years since my roommate killed my carnivorous plant vivarium...
)
Good luck, and please keep us updated!
