Photos look pretty good - much better than what I'm getting anyway - I don't have that much light in the tank and I'd imagine the flash would freak the fish out. That's my excuse and I'm sticking to it
Taking lots and seeing what works is the best way - it's the real beauty of digital cameras, costs nothing but time and also they remember exactly what you did right when you cant!

Getting things in focus at a wide aperture can be a nightmare because the depth of field is short - at smaller aperture it is longer so easier to get the right thing in focus, but the downside is less light which means longer exposures and possible blurring from vibration (as bad as not being in focus). It's a trade off..
One thing worth knowing is that you can to some extent take a photo that's a bit underexposed and then brighten it on the computer. Even if it looks almost black, the detail from the shadows should still be there. This isn't the case for overexposing things, where once it's white there's no detail left. I run my camera routinely underexposing slightly which I can correct later, so I don't overexpose the highlights which I can't.

Oh yes, and thanks for the guide on getting rid of hair algae - I can actually see the rocks again!
