You do not need a handbook on IVA's, so long as you have an IP you can visit for advice or at the very least talk to on the telephone.
Adrian, sorry I do not understand your post about the property equity. If you can reproduce word for word the provisions of your own proposal, then perhaps I can advise further.
IVA protocol is not made up as we go along - it is based upon the Insolvency Act and Rules 1986 and widespread caselaw. Of late, the creditors themselves have set rules by way of modifying IVA proposals, and it is hoped that a consistent approach will be agreed shortly. In the meantime, your IP should be the only expert you need to take advice from.
