about 370-400sq ft for smooth surface less coverage with textured coverings and no primer on plastered walls
the best way to make texture paint works on walls is to use a textured roller or sponge.. they will give nice effects to walls and give you what you want..
Using primer is necessary on interior walls or ceilings when the surface to be painted is new or newly repaired.
The best base coat for painting walls is a simple primer, usually white that will cover the wall in a simple finish. A further coat may be needed afterwards.

Try a heavy coat of primer/sealer. The primer should condition and adhere to your plaster walls. Once the primer sets up (dries) you can then apply anything you want to those walls.
If it's the standard light gray primer it should be alright.

I've never seen textured walls, but very common to spray-tex ceilings as it looks better.
No. Never use primer to change wall colors. I once bought a house that was just renovated. Everything was nice; but the walls. The renovators cheaped out and just covered the walls in white primer, it made them all feel like sandpaper.
you would want to use an oil based primer, like kilz. it has heavier stain blocking "technology".
