The models specified on within and between should be guided by your research questions and hypotheses.
(1) Yes. (2) Yes. Example 9.2 shows a random slope model. (3) There are no equalities in your model. Structural parameters are not held equal across groups as the default.
I would not use MUML. I would use the default estimator.

Dear dr. Muthen,
thank you very much for your clear reply. I've added equality constraints to my model, and found all hypothetical links homogeneous between groups, except for one; but the scale used there is very unreliable, so I'm inclined to point to power problems before I theorize a lot about it.
Due to very unequal cluster sizes (unequal classroom composition) I used MUML to handle that type of data. Is it ok to use it in this instance?
