Hi Janvf,
yes, this is a good start, I would say.
It's good to start with a small collection of modules and get to know them before you expand. And of course you will expand sooner or later ... so it is also a good idea to buy a sufficiently sized case now already. The Doepfer-case will be fine for that. With the included PSU you won't need the Uzeus, however.
So -- if you're interested in Rings or Clouds, why not watch one or two youtube-clips to find out what you could do with those? Maybe you'll then decide to swap the uzeus for one of them.
Or you might have a look at all those interesting filters out there... endless possibilities. But you're doing it just right, start with your planned combination and go slow. There's tons of cool stuff you can do with those modules already.
Have fun!
