Terence does indeed "get it". What he's trying to point out is that just posting general complaints that it's "difficult" won't get you much of anywhere here since we won't know what to advise. If, however, you post specific questions, people here will be more than happy to help.
As to the one specific question you've posed, you don't need to do three extra clicks to eject a disk. Just right-click (or control-click if you don't have your mouse preferences set to treat a right-click as the "secondary click") on the disk icon in Finder and select "Eject".
I think much of your difficulty is that you're expecting the Mac to work as your PC did. I would suggest you forget how things were done in Windows and approach the Mac as if you were just learning a computer for the first time. You might find this information helpful:

in particular the "Switching PC Habits" section.
And again, if you have specific questions, by all means post here. Lots of people, including Terence, will then be happy to offer suggestions.
Regards.
