I think I have been hacked, 1 day after I started here! Muti- questions

I have just swtitched from wp.com to wp.org. Someone signed onto my account and added themselves as a contributor. I changed it to a subscriber then changed my password. WOW.

So I have many questions. I cannot get my email subscriptions to work, I don’t know how to put a facebook like box on my side bar, I tried different plug ins and nothing seems to work. I think I got the comment form to contact me thing to work. I came here so I could get google friend connect becuase I am a crafter and 95% of my audience has google friend connect, as now it’s no longer available. I think maybe just maybe I got my network blogs straightened out..but have to wait to post again to see. I think someone from wp.com is going to transfer my email subscribers over, I don’t know where to find them. I don’t know how to use some of the plug ins that are suppose to be on the sidebar, some show up in the widgets some don’t. I need help please anyone direct me to the specific videos I need or please tell me which plug-ins work best with your new version 3.5 Blue host says every time you upgrade, alot of times the plug-ins stop working. So I take it’s a trial and error and I don’t have that kind of time with a hop coming up tomorrow! I am excited to be here and what it will do for my bloggy world, am I even a blog anymore or am I a website? Can someone help me?

One more thing, you probably can’t answer, is there a way to get my .com subscribers over?
