How can I regain Preview as my default PDF browser in Safari?

Hi, everyone...to make a long story short, I recently installed an update to Adobe Reader only to discover that it somehow took over my PDF viewing in Safari from Preview. I wanted to try and get Preview back as my default Safari PDF browser, but no luck. I trashed Reader and went into Library to trash the Adobe Internet plug-in as well. After I did that, I tried to reopen a PDF in Safari only to discover that I now can't open ANY PDF in Safari and I can't figure out how to make Preview the default reader again. I right-clicked a PDF in my computer and went under "Get Info" to try and change Preview to my default reader, but I can't figure out ANYTHING on how to regain my prior Preview default. I'm frustrated like CRAZY! I have Safari 5.1.5 and Preview 5.5.1. I would really appreciate some help on this!
