A potential solution to that first problem: If god is truly omniscient and we possess free will then perhaps god not only knows the 'future' but knows all possible futures that could come to exist given free will.
Given the talk of free will etc. it might be worth putting forward the problem of evil - that if god exists then they have created a universe in which evil exists (depends on how you define evil of course). By virtue of their free will people are able to commit acts of genocide and other atrocities. There are also issues of evil outside the realms of freewill - we have drought (though perhaps triggered by global warming etc. in more recent times), volcanoes, meteors, tidal waves, earth quakes and so on... Would one really want to side with a god who permits such things (or, could a god who possesses the attributes we normally ascribe to god and who permits such things even exist)?
