I've got a few more questions now.

If I use Aperture Priority, the exposure should be correct right..since it's controling the shutter speed? The light meter is great, but how do I know if I need to make a compensation or not?

Can you explain how I should use Auto Exposure Lock? Or should I not worry about that for now?

Btw, there's a DOF preview function, so hopefully that will let me easily set aperture how I need to based on the situation/ what I want.

I think Aperture Priority (and AF) will be a good mode to start shooting on. Any comments about this?

Thanks guys.
