Since you're used to film SLRs, you are expected to excel in dSLRs. It may look like Star Trek but its basically the same banana. Same lens in front, same viewfinder at the back, same shutter at the top right and same hump at the top. The only thing lacking is the cocking lever.
All you need is a thorough run-through of the user's manual. Your best bet is to either set it to manual or shutter priority or aperture priority, whatever you were using with film. You can even turn off autofocus if you really want to go that far. Just don't focus manually if set to auto or you'll break the lens.
Don't throw away your Minolta just yet. After you get the hang of your new digital camera, you will surely miss the cold feeling of film, the stroking of the lever, the meticulous framing and exposure metering, and finally the rewinding. You will miss raising the strips of film towards the light after developing and you will definitely miss the prints. You will eventually go back to using that film camera in the future so remove the batteries before storing in the most holiest place in your house.
