Best thing to do is probably just to buy another pot and transfer the glue over as you run out. You can theoretically use most non nylon brushes but it tends to dissolve the glue that keeps the bristles in place, so maybe rinse right away? I've used blunt syringe tips before with some success just using capillary action.

The white SpeedPaint is actually a runny light grey that shades the panels of the stormtrooper armor. If you're not sure how well a paint job will work just try it out. If you're really worried practice on some cheap toys or something and just study how the paint affects them.
Slap chop works best with models with lots of detail to catch the dry brush, but works fine on just about anything.
If you're going SpeedPaint washes aren't necessary, they're essentially a base coat and wash in one step. I would recommend some normal paints to do highlights with. Highlights are pretty tricky with speed paints.

I haven't had any problems. I usually use L.A. totally awesome from the dollar store.
Yep. I usually use a Rust-Oleum matte white rattle can when I'm planning on speed paints.
Light gray would work as well if you were planning to highlight with a white dry brush ala slap chop.
I really recommend you experiment and mess around. Paint can always be stripped, and honestly you can reprime over a paint job a few times before you start to lose detail.
If your using speed paints white all the way. You can use any matte white spray paint. Recommend doing a few test runs to get the hang of priming
Personally I like the Vallejo model color starter set, the colors are very consistent and I didn't feel like there were any big gaps while learning with it. But if you want to skip a lot of the learning and just gets models to the table I'd recommend some of the various speed painting options e.g. contrast paints, speed paints, express color etc. But if you want to learn to paint as a hobby I think the Vallejo starter set is a great set of traditional mini paints.
Do like these sculpts a lot. Great paint job. Would work well in all sorts of games.
