Starting with the bedroom suites...have your bedding selected. Choose a color that coordinates. You can accent the headboard walls with a darker color and carry that darker color into bathroom on the walls, or continue bedroom color and carry the accent color into your towels and shower curtain. I would paint kitchen and 2 dining room walls the same color, selecting a darker color for the drama in the dining room and contrast with your kitchen cupboards (such as your green color). The other walls in your living room, foyer and hallway, should be your neutral color such as a camel or warm gray. This neutral is bumping up against all of your other room colors. So, it will make a good transition from room to room. On the bold side, you could find a great wallpaper for the two walls in the dining room. Don't forget to play up your foyer with furniture for that first look impact. Selecting your bedding first, allows you to tweak your paint color and hue, and the darkness of your color. Enjoy.

On your paint problem I can't be much help. This usually happens because of damp -- please get a damp expert to make sure that there isn't any damp lurking in your walls. I had this once when I had pipes leaking inside the walls. I didn't know that. The other alternative is something like painting before the plaster is dry or some kind of chemical mismatch. I do know you will have to scrape all the mucky powdery stuff away and start again, at least on those areas. Don't try to seal and prime and repaint until you know exactly what the problem is and how to fix it.

What is opposite your desk? I think that's the only wall we haven't seen. it must be the one below in the ceiling fan photo. With the style of your windows and color of the trim, I think I'd do the walls with a specialty treatment to get the Old World plaster warmth going. You may find a wallpaper that replicates that look, if you like the look an prefer paper. The photos would tell me to turn the desk to float, centered on the window so you can look out. Your chair would face the window with your back to the bookcases, although I might move those to the wall we haven't seen. You have one full bookcase and one mostly empty. Bring in some decor items and style them with 1/3 books, 1/3 decor and 1/3 open space.

I really liked the indirect lighting and the bar light fixture.
