For your questions here is some feedback:
1) That is something for the user to input (the user needs to find these out and enter the properties)
2) That is not possible to answer – as for the second part of the question, except of materials, there are the boundary conditions loads, contact conditions between layers, and other assumptions possibly made in the FE model that might or might not reflect reality in an accurate way
3) FSUM can get the nodal forces on selected nodes

Hope this helps

Sure other members of the forum might have some comments also.
