Hi Charlie,
God's existence prior to creation is described, at least by William Lane Craig, as "timeless", not "eternal". This is akin to being a moment frozen in time.
You make a good point in that hell and heaven are supposed to be "infinite", but there are two different mathematical uses of the word. The metaphysically plausible one (denoted by a lemniscate) would apply to heaven and hell, or even the eternal future, if you don't like such religious analogies.
The other kind of infinite is a completed set of infinite members, denoted by an alpha-null. This is what a past-infinite represents.
