It's pretty hard to get 'Orange Peel' in latex. So, as mentioned several times... you need to cut back on how much paint you're putting down per coat.
I would highly advise a prime coat and then two or three very thin top coats. When rolling, you almost want to put enough pressure on the roller as if you're trying to go through your substrate. This will spread your paint much further. Not enough pressure will result in putting more and more paint down to get the entire thing covered, but then your paint surface will dry to the touch, but not the actual paint underneath, forming a wrinklie appearance.
If you don't like the fumes, then stop painting altogether and stay with pre-painted surfaces and vinyl. However, if you're a home-based set up, you need to be careful what fumes you are putting into your breathing air for all the other in the house. If you have young ones, these fumes could be dangerous to their little lungs.
Like anything else, you just don't start doing something and find out the problems afterward.... you must do your homework ahead of time to prevent these situations.
