Progress Report
I just wanted to give everyone an update and thank everyone again for their comments.
Tank
I just ordered the 30 Gallon Show Acrylic SeaClear aquarium. It is 36 Long" X 12 Deep" X 16 High with Blue background. List at Petco.com was $199, but was on sale for $173. Petco had sent me two promotions, so was $138.40 +tax, with free shipping. There is a local store by me if I have any problems.

Stand/Canopy
I am still leaning toward this stand, but have not yet bought it. It is the Red Oak 30L stand:

The retailer responded to an e-mail I sent and told me it is rated for both glass and acrylic tanks.
I decided not to get the canopy. If I decide the tank doesn't look good enough, I can always buy it later for a little more. Evaporation should not be a problem, or fish jumping.
Carpet Concern
I wrote the SeaClear manufacturer with some questions about putting it on carpet, but got no reply and could find no on-line documentation addressing carpet. I checked 3 other acrylic manufacturers' on-line documents and got mixed recommendations.
I'll make sure it is level, and may be asking shimmy questions if it is not.
Live Plants/Substrate
As far as substrate and live plants, I am still researching that. I have 25 pounds of blue gravel I bought before I realized what I was getting into. I also have some plastic plants and small caves. I will decide if to try to re-use them or if I should just start from scratch based on comments here. I will stick with freshwater.
Floor Strength
I am noy worried about my floor anymore being striong enough after what other posters here wrote and reading this:
http://badmanstropicalfish.com/articles/article28.html
"Aquariums up to 55 gallons can be placed almost anywhere without much worry at all."
My aquarium will be by the main internal load-bearing wall of my house on the first floor, perpendicular to the joists. So I see no worries here at all.
Filter/Heater/Etc
I decided to worry about the filter and heater after the aquarium arrives. I am getting too overloaded mentally otherwise. I'll then know the dimensions of the openings. I'll buy locally to make sure it'll fit before buying, and will re-read the comments here. I will buy one of those python things.
Fish/Cycling
Oh yeah, I plan on getting fish as well eventually! That'll be the fun part. My wife doesn't like them, but am thinking of starting with 2 Zebra Danios, then add one every few weeks. I plan to seriuosly under-stock the tank until I am better at this and know I can keep a maintenance schedule.
I've read five methods of cycling the tank:
1. Put one or two zebra danios in tank, but change frequently until cycled.
2. Use a dead shrimp. But I heard this gets smelly, especially for a living room tank.
3. Use amonia before fish, and let it cycle.
4. Use a agent with the bacteria people can buy.
5. Get bacteria from existing tanks. I don't kniow anyone locally.
Still deciding... but won't do #2, and will do #1 only if I can do it without overstressing the fish. Still researching.... for a 30 gallon tank, would 2 danios handle it reasonably well? or would I be cruel?
