Why do you want to move to manual? Shooting in manual doesn't make your photos better. There should be a reason why you have to do manual, for instance night photography or long exposure.
90% of the time I use Aperture priority (where I set the aperture) or sometimes shutter priority (where I set the time). Half of the time I manually adjust my ISO, and sometimes I manually adjust the exposure compensation (overexposed or underexposed). This approach is way faster than doing completely manual. If you think my approach sounds just like manual, notice that I always leave at least one element up to the camera, weather it's time or aperture. For example, if I want to do a fast shutter to capture my kids running, I couldn't care less what the camera's automatic setting is. If aperture is too large then I set the ISO higher.
All in all you just need to understand the relationship between Shutter, Aperture, ISO and Exposure Compensation. With these 4 things down you can really rely on camera's automatic setting plus your own tweak, which is much faster than manual. And these 4 things are easy to understand if you just google.
