Wow, all these assumptions. Anyway, working some things out OOC.
Clean Steve is about 15 meters from the front door. The guys in the back alley were hustling forward. The spirit did not react to Ghost's presence earlier and was still in the sky when Ghost made it back to his body. If you want to try to spring on the guy, go ahead and roll surprise with +3. So, that should be 13 dice for Jink.
Downtown, Neil's system isn't connected to the building's central node, but was accessible for the full 10 minutes where Johnny was searching the lab. Any hacking which needed to be done could be done in that blank time. It's got a firewall of 5 and analyze of 4.
When you set off the fire alarm in the building, where do you put the fake fire?
