I am working on re-doing a bedroom in my house for my baby that is currently on the way. The majority of the walls in my house have a rough painted texture. My problem is, when I repair the cracks or holes in the walls with compound and re-paint I get a very smooth area where I plastered but the rest of the wall has a rough texture. The room I am currently re-doing, I tore down 1 wall and re-sheetrocked it. This wall will be smooth but the other 3 walls will still have that rough texture. Wit hthe other walls, I have plastered area that needed it, repaired cracks etc. How can I get the rough texture to be smooth? Additional coats of primer or paint? Below are closeup photos of what I am talking about.

If not, how can I blend them together so it looks similar?

I was curious what a good all around primer I should use on bare drywall, or bare drywall with texture sprayed on it. I've used Zinsser FastPrime 2 and Zinsser 123 on already painted surfaces before in both bedrooms and bathrooms. Would that be ok to use or should I use Zinsser Gardz, SW Preprite Problock, SW Multipurpose Primer, etc... I'm looking to cover the primer with an Eggshell paint. Probably something from Sherwin Williams, but nothing to expensive. Thank you
