Is it possible to bypass the cycle if the live rock had a sufficient enough bacteria culture. There was pretty much no die off from the rock. Do you think I could start to add a few fish?

No do not add a fish until you verify your readings.
What are your readings? I would also take a sample of your tank water to your LFS to verify your readings in case your test kit is off.
