Texas General Warranty Deed with Vendor's Lien

I would love to have auction experts' opinion. I am currently looking at an auction property, and I noticed the ownership information stated two documents:

1. Texas General Warranty Deed with Vendor's Lien (Original Petition for Divorce dated 09/10/2015 recorded in Instrument)

2. Warranty Deed with Vendor's Lien

I only see one mortgage on the account, and there is a Judgement and Lien Information with a few thousand dollars. 

Question:

1. If I purchase this house, am I purchasing as the buyer of the warranty deed? or am I purchasing this as the new "Vendor" (as I am buying out the loan)

2. The lien with a few thousand dollars on the property: am I paying for it after I purchase the property? or will the seller be paying for the lien?
