Hi sinking further and welcome to the forum
I am afraid that with just two creditor an IVA is not really an option for you. They only work generally with four or more debts.
I would have thought you could afford to get a 95% loan to value re-mortgage, which would enable you to substantially repay those debts. Mortgage interest is much cheaper than loans and credit cards, although the additional mortgage payment will probably absorb all of your surplus income. At least you will only have one financial commitment to worry about.
Take advise from WelshBoy (Tony Parsons) who would be able to get you some mortgage quotations on a completely free of charge basis.
