Load bearing wall??? Can I take this down? W/ PICTURES.

Hello, I have some minor cracks and some areas that I scraped and patched that don't look 100% perfect on my plaster ceilings. They are all minor imperfections. I tried the "textured ceiling paint" route myself and it was a complete and total disaster! The sand textured paint was about as thick as joint compound, and with the textured roller, it started to splatter EVERYWHERE! I stopped after about 30 seconds, and spent the next 15 minutes cleaning up! Anyway, I was wondering if anyone had any "tricks" to hide minor imperfections on plaster ceilings. They are white now, and I will re-paint them white. What kind of paint finish should I use? Eggshell? Flat ceiling? Which one is best for hiding imperfections? Also, will it help if I use a thicker nap roller than standard, something like 1/2" nap or thicker? Will that help conceal as well? Finally, what if I use a textured roller with regular (non-textured) paint? Will it still splatter and go all over the place? Is there a certain kind of textured roller to use that will leave just a touch of texture of roughness, but not be a huge mess and splatter all over the walls? What do you all recommend? Thanks, V

Hi all, My son fell while holding one of his juice plastic bottles and dented the wall. It's about 2" across and 1" deep. Can you help me figure out how to repair?
