Ammo of Mig's One Shot primers are rebottled Stynylrez, so they say and is a wonderful primer. As is Badger's Stynylrez. As already stated they come in many colors and don't need thinning.
Vallejo's Model Air line of paints are already thinned enough for airbrushing but different humidity can affect any paint so you might need to thin it a bit.
Vallejo also has sets of colors for a lot of different subjects, AFV's, Sci-fi, Fantasy, figures. You can get a set of color for Das Afrika Corp, or German Late or Early colors, modern sets for the U.S., NATO, Russian and IDF.
AK Interactive and AMMO of Mig also have sets for different subjects. If go to their sites you can see what they have and even download PDF's containing a lot of info.

When you paint keep a fan blowing to keep the odors and vapors film building up. It doesn't need to be blowing fast and don't aim it at your work space, mine blows at the wall to the left of my benches and it's just fast enough to keep glue and paint fumes from building up.
