I *felt* nervous on slicks, but then had a couple of "just gotta ride through that!" including one that was a turn through gravel... the tires were fine. It was my head that was the trouble. That might not be true for you -- and, of course, there are semi-knobby options. How skinny are the tyres?
My Dutch Commuting bike has some really sweet wide tires that have knobs on the outside but not in the middle. It works really well.
I use WTB's All Terrainasaurus on my mtn bike for pavement and light off road use. They look to have a more aggressive tread than slicks/semi slicks but not full mtn bike tires. They don't buzz on the pavement, have good rolling resistance, corner well but also do well in light gravel or dirt. Not sure how well they would do on wet surface because they're rated for moist surface.
I agree with the let some air out. It makes a difference with ride quality and traction.
