Given the 3.3 FAQ about transporting broken units, I'd say the answer to the second question is the transported infantry count towards combat resolution. It's effectively a forced intermingling because the two formations count as one for the purposes of the engagement.
Hmm, I hadn’t noticed how contradictory that FAQ entry is compared to the main rules text:
‘Formations that dismount in this way may not take an action in the turn they dismount, but are allowed to either shoot or fight in an assault if the war engine that was transporting it is able to shoot or assault.’
I’ve always read that as meaning formations that
don’t dismount aren’t involved in the fight in any way.
