How to set default website for exchange 2010

Question

I'm unable to launch the Exchange Management Console, and then I read that it's necessary to set the default web site in a particular way, in order for Exchange 2010 Management Console to work:
http://social.technet.microsoft.com/Forums/en/exchange2010/thread/4d396628-3867-4c95-9541-e0eb021e0135
However, after setting up Sharepoint, I see that it has modified the default website, and I'd like to ask for specific settings on how the default web site bindings should look (for exchange). Could someone please advise what I need to do to correct it?
I'm having trouble interpreting what Mike Crowley recommends in the linked post above, in terms of actual steps to the site binding information (which won't mess up what exists).
Currently it says:
Type           port         ip address        binding information
net.tcp                                            
808:*
net.pipe                                          
net.msmq                                         localhost
msmq.formatname                            localhost
http            80             127.0.0.1
https          443            *
http           80              *
https          443            127.0.0.1
It seems the line for http on port 80 is *, which I guess is equivalent to 'all unassigned'. Is the previous http port 80 binding to 127.0.0.1 causing the problem?
But I'm also supposed to set a Powershell VDir in IIS. Can someone provide steps for that? 

Answer 1

Regarding SharePoint on Exchange:
It was not allowed earlier, as documented here:
http://office.microsoft.com/en-us/sharepoint-portal-server-it/coexistence-and-interoperability-guide-for-sharepoint-products-and-technologies-HA001160777.aspx & here:
http://support.microsoft.com/kb/825505 but there doesn't seem to be anything more recent than this.  I would work under the assumption it is not supported outside of
SBS 2011 (which I am not very familiar
with).
