Primer/paint coverage over old stucco

I am in the process of painting my home and am having a problem with installing primer over the stucco(this type has lots of ridges and valleys). I am using Sherwin Williams Loxon. I will then be using the SW Superpaint - 2 coats. There are several problems I am having:
1. Coverage: The SW information says I should be getting 200 sq ft/gal. I am only getting about 100 sq ft/gal. At this rate I will need about 12 gallons of primer which is too much. Is this normal coverage (100 sq ft/gal)?
2. I am also using rollers. The rollers seem to only last 50 sq ft before they lose their effectiveness. They can no longer install the paint efficiently. I am using high quality rollers 3/4 inch thick. Can you clean rollers? At this rate I will need 24 rollers if they cannot be reused.
3. Can small portable airless sprayers (such as Wagnor that can be bought at Lowes) be used to more effectively apply this primer?
4. My painter thinks the coverage is too low and the rollers should last longer. He thinks the primer is low quality.
5. Will the paint go on the primed stucco easier than the primer on the stucco?
Any advice on this would be appreciated on how to effectively install this primer.
Thanks, Rick

Airless sprayer is definitely the way to go when painting stucco. Rollers have many limitations on rough surfaces and can leave lap lines in the finish coat especially with dark colors.

I have painted MANY older stucco homes. We use flat exterior latex, have never used primer and have always gotten good results and have not had a call back to date. Not saying this is the only way to do it or even the "right" way, but this is a method that has consistently worked for us over the years. Best of all, it is inexpensive, straightforward and easy.
