Browser Clean Up

Hi,
I am trying to set the Browser Clean Up tool in the AVG AntiTrack app.  The data options that I can clean are:  Address Bar History, Adobe Flash Cookies, Browser Cache, Auto Fill Data (will delete saved passwords), Browsing History, Microsoft Silverlight cookies, Temp. Internet Files, and Web Cookies (this option will also delete saved passwords). 

Could someone tell me which of these should be cleared on a regular basis and which ones I should leave alone?  I've tried to find info on internet but can't seem to find any clear answers that helps me.  If anyone knows where I might look to address my questions, I'd be happy to follow through on my own, but right now I don't know where to start.  Thanks in advance for any help!!
