Congrats on getting the sale cancelled many times! I can't tell from your post if you are looking to save the property or just delay the foreclosure. Either way, since you don't have a date certain for an upcoming sale date (and you haven't been served with a notice) then you will receive notice before any date is set. (Sounds basic enough, but at least you know you have some time to file BK if that's what you elect to do...)
BEFORE the property goes to sale, you really have to open up judgment for any of your "assignment/record-owner" defenses to matter. At this point, judgment is entered, which means they have (technically) already "won" their case. Once a bank/lender has judgment, it uses the judgment to set up a sheriff sale to transfer legal title of the house from you to the bank (via: a Sheriff's Deed).
AFTER the sheriff's sale, if you feel that you have substantive defenses, you may consider attacking the validity of the sale by filing a motion to set aside. Use the arguments relating to Plaintiff's ownership & assignment. If you are not properly served with the Sheriff's Sale notice, use that as another defense.
You should consider consulting with a knowledgeable attorney regarding your situation; if not for representation, then at least to have someone help you understand what each document means and how you can prepare for the next few months.
Best of luck to you,

Many banks have a moratorium on foreclsoures. In NJ there is a special master reviewing the foreclosure practices of many banks and law firms. Once the special master clears the bank to foreclose they will move forward.
This has to do with the robo-signing and mortgage securitization mess. You will not find the assignments of the Note in the records of the local Clerk.
