flashlight was likely the security guards like in tian di feng jing. the spooks you see at starbucks usually blend in, not the other way around. they used to carry fake MP3 players and sit close to you and stay very quiet. once when we waved at two of them ( in their early 20's ) they looked at us, looked at eachother and then got up and bolted right away. If this was around the time when you were holding "free the slaves" meetings then I would be more inclined to think that they were spooks. But these days... they don't need people to do it anymore. Your iphone is your own personal spook. And as for surveillance in your apartment... they just need to wait for you to go out, break in ( without forced entry ) and install equipment, then leave. Don't be so paranoid man. You're definitely being watched. But not that way :P
