Hi Annette ...
As you know, there are so many things to learn in digital photography, it's a very big sea ... if you ask me, don't distribute your time for different kind of things at the beginning.
I don't know your level of Photoshop, but if you are not using Camera Raw without any difficulty, pay your attention to Camera Raw firstly. Lightroom has the same raw conversion engine with Camera Raw, so when you master Camera Raw, you also master all the adjustment sliders in the develop module in Lightroom. For the most part, Lightroom is an image management program without the develop module and, in my opinion, you will not need it at this early stage.
After mastering Photoshop, Camera Raw and your camera (of course learning process will continue after the first six months), you may try to learn about lighting, another big and main topic in photography. In my opinion, don't enter into the specific areas of photography in the first year, like macro photography (it requires special gear and without using flashes and some general information about lighting, it is difficult to master or improve it)
You may read a book about the usage of flashes and one or two books about general principles of lighting. You may also read a book about landscape photography, so you may learn more about the daylight and different kind of lights the nature gives us. Let's add them now ... one for flashes, two for lighting and one for landscape photography ... plus a book about the color management ... five books for the second half of year ... and of course, with the continuous practice with Photoshop and all the subjects mentioned in the books you will read ... then, at the end of a year, you will have all the intermediate level knowledge about the digital photography cycle, from exposing the sensor of your camera to printing your own works and all the issues between them.
Later, after one year, you're ready now for choosing the subject of your study ... portrait, landscape, macro, food, tabletop, wedding, etc. or both of them
Nothing enough, if we talk about the photogarphy ... and going from intermediate level to advanced level depends on knowledge with experience and passion with time.
My best wishes ...
