There are no stupid questions. We all started somewhere!
As the moon is just past full, using the moon filter can make viewing a bit more pleasant. As it gets closer to last quarter it is a bit easier on the eyes. Yes, it screws into the bottom of the eyepiece, or you can just rest it in the top of the eyepiece when you look at the moon. This saves fiddling about.
The 20mm eyepiece will be best for fitting the full disc of the moon in it. Magnification is worked out by dividing the focal length of the telescope, in your case 900mm, by the eyepiece size. 20mm will give you 45x magnification. The 10mm will give you 90x magnification.
Instead of a planisphere, I'd suggest getting Stellarium for your PC, it's free. For your phone or tablet, it costs a couple of bucks.
Venus and Saturn are both morning objects at the moment. Jupiter starts to rise in the west around midnight at the moment, getting earlier by about 5 mins per day.
Whereabouts in Adelaide are you?
