Speaking of learning stuff, I got these new shoes and they have these things called "laces"? Any one have any info for me? J/K
I don't think substrate has much to do with water condition for freshwater tanks. I like a little mix of the two extremes. Bare bottom/driftwood. Gives the fish something to do.

Not really. Your filter should be able to shoulder most of the bio filtration needs of your tank.

wut about a power outage?? wouldnt the bacteria in the substrate keep the fish waste in check???

You need some type of bio filter if you have a bare bottom tank.

I agree with you delgado. A decent lay of substrate promotes beneficial bacteria to grow in it. My cousin as 2" layer of a horrible blue gravel and he doesn't even do water changes!!! He has had his 40 gal for 7 years with parrot cichlids and treats the water for chloramine before he pours it in. His water conditions are always perfect!
Bare bottom tanks require weekly water changes without skipping any. More work for you IMO.
