I agree with quantum here.
There are two parts to learning music:
1) Be a mechanic.
Make sure that the airplane (that's what my teacher uses) is completely secure, even in the least paid attention of parts. Of course, no one will get that overnight.
2) Be a painter
At the same time, make sure that the music actually makes sense. Make sure that your "painting" is painted as how you want it. If the flower is black, then you are doing something wrong, and you need to change it. Playing through it just notes now, and when you get the notes, everything else will be easier, is a MYTH. It won't happen.
That's why you have to be a mechanic and an painter at the same time.
Talking about dynamics... It will go in to the painter section of practicing. However, dynamics aren't something independent. It is tone. Dynamic is qualitative, not quantitative. Therefore, worrying to play it "loud" won't help you get anywhere. You need to exercise musicality in your practice. I see that the OP is "not experienced" or whatever. Everyone plays at a different level, and should practice at different levels. However, the major components, I believe, don't change no matter what level you are at. I hope you find this helpful.
