Anyone have any good sites, or forums to learn about IIS and windows hosting and software? I would like to start tinkering with it. Thanks

http://www.iisfaq.com/

IISFaq is on the top of my list as well .. but here are some others:
http://www.iisanswers.com/
http://www.microsoft.com/technet/treeview/default.asp?url=/technet/security/tools/iis5chk.asp
http://www.adsi4nt.com/frame.htm
http://www.microsoft.com/technet/newsgroups/default.asp?url=/technet/newsgroups/nodepages/iis.asp
And of course: http://www.microsoft.com/technet/treeview/default.asp?url=/technet/security/current.asp ;)

Thank You! Now, one more question, to run apache or iis on windows? Any preference and why...Thanks

There is a install tutorial on
http://php.weblogs.com/apache_windows

However, I'd say if you want Apache you go with a Linux box. If you are gonna offer Windows hosting you should use IIS. People looking for Windows hosting are actually more or less looking for ASP.
