The trustee was politely telling you to consider amending schedules I&J to reflect your current situation. If you are making 0, you cannot have a surplus. Also, your expenses were likely too low for this area. If he/she didn't telly you to amend and closed your meeting, you should be fine.
The answer is when the judge says you have to leave. After the 30 day notice, he would have to commence a hold over proceeding. The judge may take this as a retaliatory eviction, and if you have a section 8 lease, he might not be able to evict at all. I would immediately find a landlord/tenant attorney in your area! This is one time you do not want to be cheap and whine over legal fees. A good attorney can keep you in your apartment, no attorney and you could be evicted.
Form an LLC as an inexpensive short answer. Additionally, have E&O insurance for at least $5 million if possible. A more in depth solution would involve transferring your personal assets into a trust, but if you have $5 million coverage, you can wait on the trust. As a real estate attorney for 18 years, you can never have too much insurance! If money is an issue have at least $2 million to start.
