Well dust that bad boy off and throw some paint!
About 10 years ago, a VL was my first airbrush. Though I have switched to Badger exclusively, I still remember it well enough to help a bit.
Think of your #3 tip as a 'medium' size. It will spray from a fairly fine line to about 1-1/2" pattern, and is very forgiving of most acrylic paints as long as they are properly thinned (to the consistency of 2% milk give or take.) This will be the tip and needle you use for most 1/35 or 1/72 modeling. The #1 is for very fine work, and will need very thin paint to flow well. #5 is a broader pattern, good for base coating. I almost never used ant tip and needle besides #3.
What paint brand will you be using? I am asking because yeah, Paasches are air hogs in my opinion. You will be shooting about 30 psi with Tamiya for example. Maybe 25 if you go very thin. You may want to add a bit of retarder to your thinner so your paint doesn't dry before it hits the subject. This will give a grainy appearance and texture to the paint job.
Spend a bit of time spraying something you don't care about. I use plastic milk jugs or coffee creamer containers from coffee mate. I prime them with a rattle can, then use them to test shoot a color or a new paint. Their shapes and curves behave very much like a model will.
Wow, I get chatty! Good luck, and practice, practice, practice!
