Removing "Posted In", "Tagged" " "Leave a Reply"

Hello, Wondering if you can help me figure out the below for my site WeekendPick.com: 1) On the "Homepage" and "Category Pages" is there a way to remove the text "Posted In", "Tagged" " "Leave a Reply" shown underneath the post description? 2) The fonts for my site show great when I use my iPhone or iMac but when I use my PC it defaults to Arial. Is there anyway to fix that? Best Alex
