Declination, near the meridian ??? Help!

I am reading info on some software and it is telling me the following. I am having a little trouble understanding, so some help would be great.

I think I have this correct.
Declination = Up and down with my scope
Right Assention = Left and right with my scope

Alt = Up and down
Az = Right and left

My instruction is the following: point your telescope to a 5-6 th magnitude star near 0 degrees declination and near the meridian (due south in the Northern Hemisphere, due north in the Southern Hemisphere).

I live in Adelaide so if I look at the southern celestrial pole do I assume this is 90 Declination and looking North towards the horizon is about 0 Degrees?? Then the line that passes from North to South is the Meridian? So I need to look for a star that is in the North a little to the East or West???? Have I got this all wrong? Some simple help would be great.
