Auditing Permissions and site owners

Question

My boss sent me a todo which says that he needs the following:
For each 'site':
- Farm
- Site Collection
- Site Name
- Site URL
- Site Description
- Site Owner
- MANAGER or SUPERVISOR of Site Owner
- Size of site
We have hundreds and hundreds of sites, (maybe a thousand now?), and on each one the original owner of the site has full rights to manage the users in his/her site.  On some sites there are dozens of people in the (whateversitename_Owners) SP group.
 And to make this even more challenging some sites don't have any "Owners" group, they are just granted permissions individually.
We've also learned the hard way that the Request Access email link on the sites is woefully out of date.  A spot check on that reveals at least 1/3 or more of the email addresses go to users who are no longer with the company, (we've had SP for 8 years
or so).
Does anyone know of an inexpensive tool that I could purchase that might give us at least a good chunk of this data?  And one that might be able to output that data into some kind of format that we could use to write some kind of PS script to give us
the rest?  I'm not a PS person at all, so if anyone knows of script that could help us extract some of that data as well I'd love to hear about it.
Getting the Site Owner is going to be fun, and then getting that person's supervisor or manager from AD will be another fun task.  I assume there is some way to use a PS script to get that once we get an owner defined for each site, but I'm not familiar
with how to do that.
Any help or suggestions is greatly appreciated.

P.S.  The only good thing about this request is that now MAYBE the company's management will see fit to purchase some admin tool that would do that automagically.

Try running this from PowerShell.
#Pulls site url, owner and secondary owner and writes out to output.txt
Get-SPSite -Limit ALL | Format-Table -Wrap -AutoSize -Property url,Owner,SecondaryContact,RequestAccessEmail | Out-String -Width 1000 | Out-File -FilePath SiteDetails.txt
#Pulls site url and request access email and writes out to output.txt
Get-SPSite -Limit ALL | Get-SPWeb -Limit ALL | Format-Table -Wrap -AutoSize -Property url,Owner,SecondaryContact,RequestAccessEmail | Out-String -Width 1000 | Out-File -FilePath SiteDetails.txt
