Can dl Silent in the market
I use Timeriffic to do exactly what you are trying to do...(it's free also). I have a setting to silence all rings/notifications during my work hours Mon-Fri (8:00am - 4:30pm) and enable vibrations for those and then to turn the ringers back up for phone/emails/txts after that.
You don't need any special programs. Silent mode should do it. Either your phone is messed up or one of the settings is wrong.
I have my phone on silent mode 100% of the time and it doesn't make noise for calls or notifications. I also keep the media volume all the way down unless i'm watching something.
