Hi Ed - Councils are notorious for the fine print. You may even need a licence form them to collect; which is why most collecting is done with the agreement of large supermarkets etc.
To your Qs - I'm not aware of an Hon. Secretary it's too big for that: The charity has a CEO, Bryn Parry and a committee of Governors. Use Ordnance Road, Tidworth, Wilts as the address.
Name and Address of Hon. Treasurer: No knowledge
Name and Address of Auditor: BDO Stoy Hayward
Name and Address of Bankers: Lloyds TSB, Andover
I'm sure you have all the other info re Charity No etc etc - good luck.
