well barclays loan was taken to consolate my husband debts and other loans were for the wedding

i recently got married have £7000 graduate loan with barclay. £3000 with halifax and £2000 with nationwide. my husband only has a credit card with halifax with limit up to £1200. i few weeks aga applied for halifax 15month balance transfer, which i thought we could pay off my husband credit card but i was told halifax wount transfer the money. i also applied for barclaycard and am now waiting for the card to arrive so i can pay my husbands credit card off. my concern is which card should i apply for after few months so i can pay either the nationwide or halifax loan off as i am paying a high interest on those. barclay loan is not so bad. could someone please let me lknow if i am doing the right thing. thanks
