Hello there,
I'd start by looking at the members you've already mentioned on the site.. check out their photos and pm them for tips or questions.
Also if you get really stuck you could post a ? in the how to section. I did this once when I was working on a night shot for my dio and Outrider helped me out loads with it
The guys here have all been through a similar point in their dio making hobby and we'll always try and help you out.
I read a book recently called DIGITAL Photography - Step by Step by Ben Owen.
It covers the points mentioned by Outrider above brilliantly as well as recommending photo editing packages.
ISBN 978-1-84193-544-7
