Hi Justin and welcome to the forum.
As a matter of interest why did your first IVA fail? And what have you done to improve the offer now, that could not have been done during a 14 day adjournment of the first meeting?
You will only have protection under the pending IVA, if your IP has obtained an Interim Order from Court. In reality, this procedure is rarely used these days, unless there is a direct threat to assets such as a Charging Order or Bankruptcy Petition pending.
The fact that some of your debts have been referred to collection agents is irrelevant in the short timescale between now and your meeting. Most of these companies are toothless, but you should continue to advise them of the situation. Also make your IP aware of this, as he/she will probably need to send them copies of your proposals.
Good luck with your second attempt - a shame it didn't work first time.
