foreclosures in oklahoma

I’m new to rei (suprise!), and very interested in the foreclosure process. Can anyone explain how it goes down in oklahoma?

I know that I can search for Lis Pendens here: http://www.oklahomacounty.org/coclerk/deeds/RofD_Search_03.asp

and I know that Sheriff’s sale notice info is here:
http://www.oklahomacounty.org/sheriff/SheriffSales/SaleNotice.htm, but contains very little info.

Can someone spell out the basics for me? Thanks!
