If you are going to be brush painting your enclosures, ensure that you condition your paint before applying it. One such product is Floetrol and is sold in quart-size containers at Home Depot and Lowe's for about $4.00. The container of conditioner is enough to condition a few gallons of paint. The conditioner does not dillute the paint, but makes it easier to work with. I recently used this product while refinishing some furniture with paint and the paint turned out very good - much better than if I had utilized just the paint alone.
I'd say gloss, satin, egg shell etc are more of a sheen not a texture. It's how shiny the paint is when dry.
Some places use satin and egg shell interchangebly.
From Wayne's list, bottom up is easy of cleaning too. High gloss is much easier to clean than egg shell. That's why most kitchens and bathrooms are semi-gloss or high-gloss and most others rooms are egg shell.
Textures would be how smooth or rough the surface is when dry.
