Recovery time is important, of course. You can do that the whole rest of the day.
Its fine to do a circuit set, even if you want to build muscle. Its simply going to tear down more muscle fibres at a time, keep your heart rate up, etc. Its actually great for getting through plateaus on your lifts; at least personally in my experience. Plus you're still challenging yourself strength wise, and as your body fatigues, you're training your body to get stronger at its weakest, that way becoming stronger at its strongest as well.
Your rest between sets is important for your strength lifts, if you're going extremely heavy doing heavy singles or doubles. You want a 3 or 4 minute break in between each lift. But this circuit type set shocks your system, breaks down your muscle, and is actually a very good muscle builder.
