The only significant debate in terms of fiscal powers was on the Scottish Parliament's borrowing abilities. Basically, they didn't have any - less than a local authority, for example. The Salmond administration followed the Labour principle of spending to get us out of recession and, despite funding coming from London, suggested that it was a lack of these powers that was buggering the economy.
The Scotland Act 2012 now legislates for fairly significant borrowing powers for Holyrood, although they won't come in for a couple of years yet.
