Well the County Clerk and in Monmouth County, the Hall of Records, are the places to go to obtain some of the information you are seeking. At the County Clerk's office you will be able to request a property report and that will show you the secondary liens on the property.
What do you mean the house might settle? If you are referring to the homeowners settling with the bank that is a very, exceedingly rare circumstance once the Sheriff's Sale date has been assigned. There are two statutory deferments of the date. These exist ostensibly to allow the homeowner to attempt to come up with the money and to find another place to live. But I don't know if I've ever seen a homeowner come up with the money.
As for the starting bid, the bank has to make the first bid and it will always be the deficiency owned on the mortgage. On many properties purchased during the real estate boom between 2004-2007, the deficiency will be far greater than the value of the house. Many times you will have a $300,000 house with a mortgage deficiency of $500,000. You need to do your research so that you are not wasting your time at auctions. Many of these properties become REO and when they re-hit the market you will have a shot at them but you will also be in competitive bidding wars on the good ones.
Your best bet is to work with a wholesaler and/or make sure you are only going to the Sheriff's auctions for worthwhile properties. There are obviously some good auction properties but there will also be a lot of competition.
