Full slate of fund-raising and others

There are some things I didn't understand here (As usual lots of doubts so thanks )

What is "Full slate" ?

Combined to a gin up buzz ?

Generated here means gained? and what is Material in this context?

"his successful memoir, Dreams from My Father—for which
there would be an extensive promotional tour. Those
events, together with a full slate of fund-raising and
campaigning in the fall for Democratic candidates
competing in the midterm elections, could be combined to
gin up buzz, and also to measure how much of the energy
Obama generated might translate into material support for
a presidential run."
