Allegheny County sheriff sale question

[Dan Porter]

Just wondering if anyone has experience with sheriff sales in Allegheny County? The sheriff sale listing looks like the below image as an example (I am not interested in this specific property). 

Can someone help decipher this? If I were to be the winning bidder on this property, then I would pay the bid amount + $44,146.76? Is that amount all due taxes and liens on the property? Or should I consult an attorney before purchasing a property? What should I expect to pay for an attorney looking into this for me? What do the checked/unchecked boxes in the top right of the listing? Are the dates listed below payments that the defendant is required to make? 

All comments/help is greatly appreciated!! This is a new area of investing for me, but I would like to get into sheriff sales for the extra margin when doing flips/BRRRs. Thank you much!
