Hi DW, long time...
We'll forego the 'what god?' schpiel this time!! Or shall we?
Obviously you are talking of the Judaeo/Christo/Islamic god, prehaps more specifically still the Christian Biblegod.
1) Does God even need time or space to exist?
From the Bible, this answer would by inferance be 'no'. God originated space and time, so therefore existed before them, so therefore doesn't need them.
2) Does he look at time the same way we do?
From the Bible, a thousand years are as a day in his eyes. One assumes this is something like how summer days lasted forever when you were five, and now last five minutes, but taken to the extremes one must with a indefinate entity.
3) Does he view past, present, and future as all the same?
Only if he is an idiot, as demonstrably past, present, and future are different.
Those are really rather elementary questions; two are answered form the Bible, one from logic.
What is more interesting is, does god perceive the future, i.e., can he fortell future events, and if so, with what accuracy? The accuracy of a skier knowing THAT slope is dangerous, or the accuracy of a sports-commentator pointing out where the skier went wrong when looking at a replay.
This has knock-on questions which can inevitably bring us back to the 'what god' question!!
All the best
