Warden forum will have lots of info for you, since Wd/S is one of the most popular warden builds.
In brief, though.... Wardens are not ranged, but Chiron is. Wd/S exclusive pet and the best pet by far. You should use 2-h axe as your main weapon. Dual class is a system where you switch between classes and one becomes your current primary, another current secondary. You get general skills for both classes, the class specific from primary only. You also get elite skills that are particular to the class combination. Theromwiki.com should give you good overview on those skills.
-- Rustyx --- 92R / 92S / 92M on Reni (Guild KnightShift). Yes, running the new FOTM R/M, cause I am not elf enough to be WD/S.
Oh, and people who have more than 3 classes are clinically insane.
