If so was it contracting before the big bang which lead to it expanding now?

The most recent research into your subject (..the WMAP probe..) strongly suggests that our universe will continue to expand indefinitely. As for conditions, if any, before the Big Bang we have absolutely no way of determining this.

hard to say.
the three choices have been:
1) the Universe is static
2) the Universe is a yo yo...
3) the Universe is expanding.
#1 kinda fell apart a little less than a century ago when we first discovered Red Shifts... seems like everything in the Universe... nearly... is running away from us. (smatter? didnt we shower?)
#2 and 3 are the leading contenders at the moment, with 2 pulling ahead by a nose. Of course any day now we might discover that Dark Matter is giant space goat feces and is much more common than we thought.
Until we run into the goats.

Existing laws of physics say yes that our universe will expand for all eternity...that is to say if there is no wall around our universe to contain it's expansion.
According to Sir Isaac Newton all objects in motion will remain so until an imbalanced force is applied. Since our universe is a bunch of objects floating in a vacuum I'm lead to believe that everything in it will keep moving at it always has...unless that is to say there's a wall coming up that will stop us by applying this unbalance force. Until we see this force we would be inclined to say there's nothing stopping the universe from expanding so it will expand indefinitely.

This is interesting , nothing lasts forever . Imagine a balloon
that never pops . That's one big balloon ! Eventually It will pop at some point . I don't think our universe has to worry about this for ten billion years , but one day a rip may occur .
