Two basic questions here, thanks and good karma to whoever helps. my questions are:

The spin of an elementary particle, is it really the physical rotation of a particle on its axis?

and

Can I imagine that an elementary particle looks like a three dimensional wave packet laying/distorting the assumed higgs field?

1) no, spin is sort of an intrinsic angular momentum; however, it cannot be modeled as a particle actually spinning. As far as we know, particles are points and therefore can't really spin.

2) I have no idea.

Spin: i agree it is always confusing..It is not the rotation or spinning..
For e.g., there is only two kinds of spin for a electron 1/2 or -1/2.
It is better if you think of Pauli matrices..

So okay, this intrinsic Angular Momentum.. is it expressed by the literal "spin" particles create after they collide?

So far I understand that particles are "born" with this property of spin. Pauli Matrices I do not yet understand. I've wiki'd spin but would just like the layman's version please.
